Chapter 375 The Birth of a Genius and a Champion!

PS: After writing the game in one breath, there should be more than 10,000 words, not to be missed!

——

"Congratulations to Imperial College for being the first to solve [Problem B] in seconds!"

Following the announcement of the competition committee, behind the area where the three contestants of the Imperial College London team were located, a balloon marked "FIRST-PROBLEM-SOLVED" was raised.

This is the honor of the first team to solve each problem.

When he heard that it was Imperial College, Huang Youjie was a little disappointed. He thought it might be Abin and the others who solved [question B].

"Imperial College of Technology is very strong, there is no doubt that it takes seconds, it is very powerful." Ding Yue couldn't help frowning.

If this trend continues, will my Wucheng University of Arts and Sciences fail to enter the final championship competition?

The competition system of the ACM competition is to count all the accumulated time for answering the questions. The shorter the answering time, the higher the chance of winning the championship.

If there is still the last question left, the gap in answering time between many colleges and universities is only a few minutes, and in ten minutes, there is a chance to catch up with the last question.

Even if it is a difference of twenty minutes or half an hour, there is hope.

I am afraid that those colleges and universities with perverted strength will solve the first few questions in about ten minutes, so they have opened a bigger and bigger distance from other colleges and universities.

beep!

"Wucheng University of Arts and Sciences successfully passed [question B] in seconds!"

The sudden sound of the announcement of the competition committee immediately made Ding Yue aroused!

Your own Wucheng University of Arts and Sciences!

It was the second college team that solved [Problem B], which surprised Ding Yue.

For the first question, the time ranking is relatively high. This second question is directly second, and the difference from the first one to solve [question B] is only 17 seconds. Not a difference at all.

"Brother Yue, Abin and the others are awesome! Did you solve this problem so quickly?" Huang Youjie grabbed Ding Yue's arm excitedly after hearing the announcement from the competition committee.

"Hahaha, it seems that Abin didn't disappoint me. Chen Jun and Ouyang Chen are not bad either."

With such a good result, Ding Yue is naturally happy.

Combining the time spent on the first question and the second question, Wucheng University of Arts and Sciences may be among the best, right?

Then, St. Petersburg State University, California Institute of Technology, Nanyang Technological University, Haicheng Jiaotong University, Moscow State University and other colleges and universities also passed [question B], and everyone spent almost the same time, at most one or two time interval in minutes.

These are all participating colleges and universities in the first echelon, and their strength is very strong in all aspects.

As an opponent, it must be taken seriously.

Afterwards, more than a dozen other colleges and universities also passed [Title B] one after another, including Northwest University of Science and Technology from Xia State.

And this time, the University of Cape Town in Africa is not the only university that failed in [Question B]. In addition, there are three other universities that have problems when solving [Question B].

In the end, the 30-minute answering time passed, and the four colleges failed to get the grades.

In this case, the University of Cape Town from Africa completely lost the chance to compete for the ACM championship.

Then about 30 other universities are currently divided into two echelons. The first echelon is St. Petersburg State University, Imperial College of Technology, Caltech, UC Berkeley, Haicheng Jiaotong University and other powerful universities.

Of course, Ding Yue's Wucheng University of Arts and Sciences is also in the first echelon? And after answering the two questions, the scores are in the forefront of the first echelon.

Is this question more difficult than the other question? The competition became exciting from the beginning of [Question C].

Because when the competition committee released the third question? All the college teams are busy answering the questions.

This time, no college has solved [question C] in ten minutes? The most important thing is that the answering time given by the competition committee for this question is actually 45 minutes.

The time to answer a question has increased, which also means that the difficulty of the question has risen sharply.

The University of Cape Town team is not a very strong university? When faced with [Question C]? I am a little overwhelmed.

"This program doesn't seem to have a solution!"

"Impossible, will the competition committee issue an unsolvable problem?"

"Then can you try to solve it in C language?"

"Even, this is really too difficult, or it's impossible at all."

The participating teams of several colleges and universities with relatively low grades? Suddenly stumped by this [question C]? It is like a roadblock.

Through this question, the teams with strong computer skills and the teams with poor computer skills were completely distinguished.

The college teams in the first echelon did not show any difficulty when faced with this problem, and everyone was solving the procedure in an orderly manner.

With the strong assistance of his two teammates, Xu Bin can write programming like a duck to water.

This problem is indeed very difficult? But for a computer genius like Xu Bin, this difficulty is nothing more than a slightly more complicated process of writing programs? It is not an unsolvable programming problem.

Like Xu Bin and the others, the players of the other first-tier college teams are all calmly programming to solve this problem.

As for the contestants of the second-tier college teams, some of them performed well? Treat them calmly like the first-tier colleges and universities.

In some cases, the three of them started to discuss.

Discussion? Does it mean that they didn't have a problem-solving idea in the first place? This is a huge waste of time.

After all, the competition of the ACM International College Student Programming Competition is who can solve the programming problems given by the competition committee faster and more efficiently.

Twenty minutes passed.

The arena is still very quiet, and the first college team to solve [Problem C] has not yet appeared.

Even Ding Yue couldn't help holding his breath, thinking in his mind is this problem so difficult?

The first two questions basically passed ten minutes later, and colleges and universities began to solve them one after another. Now this question has been solved for twenty minutes, and there is still no movement.

[Live Room of Science and Education Channel of National Television Station]——

"I'm a computer major. With all due respect, I was dumbfounded by this question."

"Twenty minutes? Still no team has solved this problem?"

"It's very difficult Azi."

"This question should be a good opportunity to score points, Haicheng Jiaotong University, let's go!"

"Wucheng University of Arts and Sciences rushed!"

"Northwestern University of Science and Technology is going to rush for you!"

"It's over, the third question of this ACM competition, I am basically a computer student who can't understand it."

"It is really difficult, and this problem is very complicated to solve."

"Yes, yes, it's not only complicated, but if you are not careful, there will be program errors. It's very difficult."

In the live broadcast room of National Television's Science and Education Channel, more than 20,000 viewers came from Wucheng University of Arts and Sciences.

This ACM international college student programming competition is very important to Wucheng University of Arts and Sciences.

Because this is the first international competition of Wucheng University of Arts and Sciences, many students of Wucheng University of Arts and Sciences are spontaneously paying attention to the competition.

beep!

game scene.

Finally, the voice everyone was familiar with rang out.

"Congratulations to Moscow State University for successfully solving [problem C] in seconds!"

boom!

Following the announcement of the competition committee, an orange balloon with the sign "FIRST-PROBLEM-SOLVED" was raised behind the three contestants of Moscow State University.

In fact, each balloon is a different color.

"It seems that each question that follows should take more and more time." Ding Yue said with emotion after seeing that Moscow State University successfully won the first place in this question.

The time for this question is almost doubled compared to the previous question.

"Moscow State University is very strong. It has almost won the ACM competition with St. Petersburg State University in recent years!"

Huang Youjie said with his mobile phone in his hand.

He just checked the information, only to know that Moscow State University and St. Petersburg State University seem to have won quite a few times in the ACM competition in recent years.

"I just want to know when Abin and the others will solve this problem!"

Ding Yue's expression became a little dignified.

If each of the following questions takes a long time, then the variables behind may be relatively large.

For example, St. Petersburg State University, which passed the first question, has not yet solved this question.

beep!

"Haicheng Jiaotong University successfully passed [topic C] in seconds!"

The second solution to [Problem C] was Haicheng Jiaotong University.

It seems that it is worthy of being the most promising university in China, with extraordinary strength, and even has the opportunity to compete for the championship.

beep!

"Imperial College successfully passed [question C] in seconds!"

beep!

"Wucheng University of Arts and Sciences successfully passed [topic C] in seconds!"

Soon, two consecutive colleges and universities solved this problem in less than five seconds.

And one of the colleges is Ding Yue's Wucheng University of Arts and Sciences, which is almost better than Imperial College's score on this subject.

"The gap is not big, the gap is not big, it's okay!" Ding Yue breathed a sigh of relief after hearing the time results of his Wucheng University of Arts and Sciences question.

The difference between the first place and the first place is only one minute, and this minute has little influence on the following questions.

"President Ding, our Wucheng University of Arts and Sciences seems to have achieved good results after these three questions."

Wen Ruohan said happily.

"Well, I can only say that it's okay." Ding Yue glanced at Wen Ruohan who was very excited, and said, "It has to be stable until the end of the game, and then other colleges and universities will come and go, so there should be a chance. "

When Ding Yue mentioned other colleges and universities one after another, he meant that they were like St. Petersburg State University in the first question, California Institute of Technology in the second question, and Moscow State University in the third question, although one question was The first one is solved, but as long as it is a little slower later, the time score will be leveled.

On the contrary, like Ding Yue's Wucheng University of Arts and Sciences, the scores of each question are relatively high, and the time gap between the first and second places is not large.

In this way, Ding Yue's Wucheng University of Arts and Sciences may still be ahead in time.

However, the grades of St. Petersburg State University have always been relatively good, and Caltech, like Ding Yue's Wucheng University of Arts and Sciences, has not won the first place, but its grades have always been in the forefront.

Sometimes even better than Ding Yue's Wucheng University of Arts and Sciences.

45 minutes have passed.

In the end, only 25 colleges and universities passed [question C]. This time, this stumbling block directly blocked nine colleges and universities. It is conceivable how difficult the next question will be.

"Brother Yue, every question after this will be more difficult, right?" Huang Youjie, who was sitting beside Ding Yue, couldn't help asking.

"That's for sure. Every question that follows will bring down one university after another. If one question is not solved, then it will basically miss the championship."

Ding Yue nodded and replied.

"Then Abin and the others must not make mistakes!" Huang Youjie suddenly became nervous.

This third question has already stumped nine colleges and universities. Huang Youjie can't be nervous.

Ding Yue, however, calmed Lao Huang's nervousness, and said with a smile, "Old Huang, we have to trust Abin and the others."

Actually.

Ding Yue said so, but he didn't have any bottom line in his heart. He believed it, but whether he could pass the customs all the way is really unknown.

At that time, the sixth and seventh questions, wouldn't it be difficult to go to heaven?

With the end of the time for the third question, the competition committee soon opened the fourth question.

After all, the total time of the competition is five hours. Although it may be extended for various reasons, too much time should not be wasted between each question, because the longer the interval, the easier it is for the contestants to get hot and confused. The feeling of thought disappears.

[Title D] appeared.

In the competition area of ​​Wucheng University of Arts and Sciences, Xu Bin was sitting in front of the computer, with Chen Jun and Ouyang Chen on the right.

"Director Xu, this is a security loophole completion program." After analyzing [question D], Chen Jun said to Director Xu Bin: "It seems difficult, we can pass..."

If Chen Jun is to solve this problem alone, I am afraid that Chen Jun has no idea.

But this is a three-person team, and with Director Xu Bin in charge, Chen Jun is not so worried.

"Security breach?"

After hearing Chen Jun's words, Xu Bin couldn't help but look at this question.

Xu Bin likes programs with security vulnerabilities.

Xu Bin has been working on a security system since he started studying computer science at Wucheng University of Arts and Sciences.

At present, all the basic network equipment in Wucheng University of Arts and Sciences has a security system, which was independently developed and designed by Xu Bin.

Starting from the fourth question, almost all the three contestants of the college teams were discussing for the first time.

That's right!

For the first three questions, many colleges and universities have already started to write programs to solve bugs after seeing the questions.

And the fourth question, if you want to complete it in an efficient way, I am afraid it is not so easy.

"If the first three questions are appetizers, then the fourth question begins, and the real difficulty comes."

"It doesn't look like this problem is solved very well."

"I have to say that the annual problems of the ACM competition committee are very difficult, and those who can successfully solve the seven problems are all at the top level in the world."

Many audiences who love computer programming at the scene began to talk about it.

There are actually many computer experts among these live audiences. After all, the influence of the ACM competition is still quite large.

However, even a computer expert, when faced with the fourth question, has to sigh that this question is actually quite difficult.

But these computer experts did not say that the problem could not be solved.

The solution is definitely solvable, and it depends on how the participating teams of various colleges and universities solve it.

"This security loophole looks exaggerated, but it's actually not that difficult." After reading the topic, Xu Bin began to fix the security loophole.

The fourth question is to let the participating college teams fix this security loophole through procedures.

Since we want to fix this security hole, we must first understand what the programming code of this security hole is.

This is the first major hurdle for many colleges and universities.

But for a computer genius like Xu Bin who has been exposed to countless security vulnerabilities, this does not seem to be difficult.

Soon, Xu Bin found the programming code of this security vulnerability almost immediately.

Then start fixing based on security holes.

The competition committee gave a full hour for this question. It can be seen that the competition committee has a very high evaluation of the difficulty of this question.

"Director Xu, do you understand the programming code of this security loophole?" Chen Jun asked in surprise when he saw that Chief Xu Bin started to fix the security loophole directly.

While others are still analyzing what kind of programming code this security vulnerability is, Director Xu Bin is already on the way to fix it.

This means that Director Xu Bin is a lot ahead of other universities in this question!

"I've been in touch. I've built a security system and tried a lot." Xu Bin said to Chen Jun while fixing the security loophole, "It's a coincidence."

After Chen Jun heard the words, he didn't ask any more questions, because if he asked again, it would probably delay Director Xu Bin's time to fix the security loophole.

In this question, the roles of Chen Jun and Ouyang Chen have become much smaller all of a sudden, basically belonging to Director Xu Bin's personal show.

When Ding Yue saw in the backstage lounge that Xu Bin seemed to have started writing programming codes to fix security vulnerabilities, he felt a little excited.

"It seems that Abin is determined to win this topic!" Ding Yue said excitedly.

"Really? Huh? Abin has already started fixing the security loopholes? The contestants from other colleges and universities are still discussing it!"

Huang Youjie also saw the scene of the game through the screen in the lounge.

The pictures of 34 college teams can be seen, and most of them, including the three players in the first echelon of St. Petersburg State University and Imperial College of Technology, are still discussing how to fix this security loophole.

And Xu Bin from Wucheng University of Arts and Sciences has already started repairing it. Chen Jun and Ouyang Chen on the side seem to have completed the task, and everything is handed over to Xu Bin, who is responsible for programming and fixing security vulnerabilities.

Gradually, more people began to pay attention to the team players of Wucheng University of Arts and Sciences.

The way they solve this problem seems to be different from other participating colleges and universities. They started to fix the security loopholes without much discussion?

Seconds later, the jury group of the competition committee received the "answer sheet" submitted by Wucheng University of Arts and Sciences.

"Has this security hole been fixed so soon?"

One of the judges of the jury team looked at several colleagues around in surprise and asked.

"Let's take a look first, this security vulnerability program, according to past experience, takes nearly 40 minutes." Another judge of the jury team said.

Then the judges began to rate the "response" submitted by Wucheng University of Arts and Sciences.

After about three minutes.

"This... actually fixed the security hole!"

The judges were all surprised!

[Question D] is the only security vulnerability programming question in the ACM competition, and the difficulty is naturally very high, otherwise it is impossible to give a full hour of answering time.

In seconds, the participating team of Wucheng University of Arts and Sciences has successfully solved and repaired this security loophole.

For the judges on the panel, it was incredible!

"Genius, to be able to fix this security loophole so quickly, I have to say, this is a real genius!"

A judge named Smeagol said with emotion.

"Pass, announce it!"

The judges of the jury panel unanimously determined that the "answer sheet" submitted by Wucheng University of Arts and Sciences has indeed successfully repaired the security loophole.

beep!

Just when the other 33 college teams at the competition site were still seriously fixing the security loopholes, a frightening voice sounded.

"Congratulations to Wucheng University of Arts and Sciences for successfully solving [Problem D] in seconds!"

The sound fell.

Immediately with a "bang", behind Xu Bin, Chen Jun, and Ouyang Chen, the red balloon that marked "FIRST-PROBLEM-SOLVED" finally rose.

I don't know if it's a special design or a coincidence, but the first balloon raised by Wucheng University of Arts and Sciences after solving [Question D] is actually red. Does this mean that it is the red of the East?

Maybe it's just a coincidence.

"Principal Ding, the red balloon, Director Xu and the others are great too, they were the first to solve this problem! It's amazing!"

Wen Ruohan was already excited when he saw this.

After all, this is the first time that Wucheng University of Arts and Sciences has solved a problem first, but Wen Ruohan doesn't know if seconds are fast.

In fact, Ding Yue doesn't know if this is fast or not. It depends on how long it takes for the second place to pass [question D].

Only the judges of the jury group of the competition committee know that the second time has broken records in the past security bug fixes.

"Wucheng University of Arts and Sciences are they so fast?"

A contestant from Haicheng Jiaotong University, also a participating university in the Xiaguo Division, exclaimed.

"It's fast enough, it's a bit BT, but don't waste time, hurry up and fix the security loopholes." Another contestant from Haicheng Jiaotong University said quickly.

As shocked as the contestants of Haicheng Jiaotong University, there are many colleges and universities, such as St. Petersburg State University, Imperial College of Technology, Caltech University, Moscow State University, etc., their contestants are also hearing the fog. After Chengcheng University of Arts and Sciences was the first to complete the repair of security vulnerabilities in seconds, they were dumbfounded.

Some were dumbfounded, some were happy.

The happiest of course is Ding Yue.

"Hahaha, Abin really didn't let me down, so I started to win first." Ding Yue nodded contentedly.

At the same time, Ding Yue is also calculating silently in his heart, how long will it take before he can rank first for the time being with the accumulated time grades of Wucheng University of Arts and Sciences?

At present, the cumulative time scores ranked ahead of Wucheng University of Arts and Sciences include St. Petersburg State University, Moscow State University, Imperial College of Technology, California Institute of Technology, Haicheng Jiaotong University and the University of California, Berkeley.

A total of six.

Among them, the time difference between Haicheng Jiaotong University, UC Berkeley and Wucheng University of Arts and Sciences is actually less than 30 seconds.

Now, 30 seconds have passed.

And the two universities still haven't solved the problem of this security loophole.

This also means that the current cumulative time score of Wucheng University of Arts and Sciences has surpassed that of Haicheng Jiaotong University and the University of California, Berkeley.

The time gap between the first four colleges and Wucheng University of Arts and Sciences is at least 1 minute. Even because St. Petersburg State University won a first place, the current time gap between Wucheng University of Arts and Sciences is more than 5 minutes.

For the next 4 and a half minutes, Ding Yue's mood was always uneasy.

However.

Four and a half minutes passed quickly.

At this time, Ding Yue was both surprised and puzzled.

what happened?

Why haven't other colleges and universities solved this problem of security vulnerability repair?

At this time, even if St. Petersburg State University passed [question D], the time achievement would not be able to surpass Wucheng University of Arts and Sciences.

Temporary first, has been firmly grasped.

[Live Room of Science and Education Channel of National Television Station]——

"Hahahaha, our Wucheng University of Arts and Sciences is awesome. Now we can rank first in time, right?"

"This is amazing, and the problem of security vulnerability fixes has been solved so quickly."

"Is it the first?"

"What? Wucheng University of Arts and Sciences won the championship?"

"Uh uh uh, don't talk nonsense, it's just that the temporary result should be the first. It's hard to say that winning the championship. After all, there are three questions behind, and one question is more difficult than the other."

The domestic audience is already boiling.

To everyone's surprise, Wucheng University of Arts and Sciences actually took the lead for the time being. It seems that everyone had underestimated the strength of this university before.

In fact, many people think that the Wucheng University of Arts and Sciences this time, there is an element of luck, and it is just soy sauce.

But from the first question to the fourth question, everyone has seen it, and the performance of Wucheng University of Arts and Sciences has always been very good.

Until the fourth question was solved so quickly, it completely changed everyone's view of Wucheng University of Arts and Sciences.

Now, among the three domestic universities participating in the ACM competition, the strength of Wucheng University of Arts and Sciences and Haicheng Jiaotong University have been recognized by the audience, and everyone believes that these two universities have a chance to win the championship.

As for Northwestern University of Science and Technology, it can only be said that there is indeed a slight gap in strength, but Northwestern University of Science and Technology is in the second echelon, and its results are quite good.

However, Northwestern University of Science and Technology is basically out of the race for the championship based on its current time performance.

Unless Northwestern University of Science and Technology suddenly emerged in the seventh question and solved the problem in super fast time, it is almost impossible.

As we all know, the seventh question is simply difficult to get to the sky.

Thirty-five minutes have passed since the fourth question was solved. Ding Yue took a deep breath and wondered if it's been 35 minutes, or haven't other colleges and universities fixed the security loopholes?

This!

It's so cool!

Because the further back in time, it means that the Wucheng University of Arts and Sciences will have a greater advantage in this question.

beep!

Finally, after another minute or so, the "beep" sounded.

Immediately afterwards, the competition committee announced: "Imperial College of Technology successfully passed [question D] in seconds!"

beep!

"St. Petersburg State University successfully passed [question D] in seconds!"

beep!

"Caltech successfully passed [question D] in seconds!"

beep!

"Haicheng Jiaotong University successfully passed [topic D] in seconds!"

Since Imperial College successfully repaired the security loopholes, the successive universities with the strongest first echelon have also successfully completed.

The gap between everyone is not big, but compared with Wucheng University of Arts and Sciences, the gap is big.

The time for this question is almost ten minutes short!

On the other hand, St Petersburg State University is a bit arrogant. This question is less than ten minutes away, plus his five-minute advantage.

This means that there is actually a difference of about three or four minutes between St. Petersburg State University and Wucheng University of Arts and Sciences.

Ding Yue remembered this St. Petersburg State University, which was the biggest competitor of his Wucheng University of Arts and Sciences on his way to winning the championship.

Of course, in fact, strong universities such as Imperial College London, Haicheng Jiaotong University and California Institute of Technology should not be underestimated.

The fourth question suddenly made a big change in the results on the field.

Some colleges and universities that were originally the first echelon actually fell directly to the second echelon because of this security vulnerability repair problem.

And some colleges and universities in the second echelon, because it took more than 40 minutes to solve the security loopholes, entered the first echelon again.

But those college teams at the back of the crane are basically the same, and the food is still the food.

Especially the University of Cape Town from Africa, they failed [question D] again and again.

It seems that every question is difficult for the three players of the University of Cape Town team. I wonder how their alumni feel when they see the competition?

After the fourth question is over, who has a chance to win the championship and who is just here to play soy sauce will all be clear at a glance.

The fifth question does not seem to be as difficult as expected.

Moreover, the time to solve the fifth question given by the competition committee is only 20 minutes, which is actually the shortest time to solve a question.

However!

The short duration of this fifth question does not mean that it is not difficult.

It is because there are not many programs required for this problem, but it is really difficult. Many second-tier colleges and universities have racked their brains and still do not know how to solve this program problem.

The top colleges and universities in the first tier are still very calm.

It seems that even the fifth question can't help them.

With the perfect cooperation of Chen Jun and Ouyang Chen, Xu Bin took a second to pass this question with the third place.

The time gap between the top two and Wucheng University of Arts and Sciences is at most one minute.

This means that although Wucheng University of Arts and Sciences is not the first to solve the fifth question, the current cumulative time score, Wucheng University of Arts and Sciences is still temporarily ranked first.

"If this can be stabilized, it seems that we have a chance to win the championship!" Huang Youjie looked at the cumulative time score after the fifth question was about to end.

Wucheng University of Arts and Sciences temporarily ranks first, St. Petersburg State University second, Imperial College of Technology third, California Institute of Technology fourth, Moscow State University fifth, Haicheng Jiaotong University sixth, Nanyang Technological University seventh, University of California, Berkeley Eighth, ETH Zurich ninth, Stanford University tenth.

Speaking of which, Stanford University is a super well-known world-class university in the Eagle sauce country, and it is also among the best in the global rankings, sometimes even in the top three.

but!

In the ACM competition, Stanford University's performance is not very good, it may be that the strength of their three participating teams is indeed compared with the previous universities, there is still a certain gap.

At present, it seems that the favorites to win the championship are obviously the colleges and universities in the top ten.

Ding Yue is looking forward to just as Lao Huang said, as long as his Wucheng University of Arts and Sciences is stabilized, will the championship soon be at hand?

But the sixth and seventh questions are coming soon. Whether this can be stable or not is really a big question mark.

If you can win the championship, you can be a blockbuster, at least in the field of computer science.

If you can't win the championship, even if you shine in the fourth question, it will be useless, because in the end people only pay attention to the championship.

"call."

Ding Yuechang sighed and said to Lao Huang, "I hope Abin and the others can stabilize. Of course, it would be great to be able to create a score like the fourth question."

"yes!"

While Ding Yue and Huang Youjie were chatting, the competition committee announced that the sixth question had begun.

The difficulty of [Question F] is directly full, and it takes one hour to answer the question, of course, the time specified by the competition committee at this time.

That is, the question [question F] must be solved within one hour, otherwise this question will be regarded as a failure, and if the question is not passed, the score will not be obtained.

For those college teams who have the opportunity to compete for the championship, if this question fails to get results, they will directly GG.

The difficulty of the sixth question is beyond the expectations of many colleges and universities.

"This...it's almost impossible!"

"too difficult!"

"An hour? I may not be able to do it in a day!"

"Mike, start now!"

"Hurry up, hurry up and try it!"

Many participating students from well-known colleges and universities were a little discouraged after seeing the sixth question.

In fact, even Xu Bin frowned.

Chen Jun and Ouyang Chen on the side also looked anxious.

"Director Xu, I'm afraid Ouyang Chen's analysis of this question is not enough." Chen Jun said to Director Xu seriously.

"I know, but it doesn't matter, let's try to solve this problem together, you can provide ideas as much as possible."

Although Xu Bin frowned, he did not panic.

Because he knew that he had to be calm at this time, and once he got into a mess, he might not be able to solve this problem in an hour.

It is said that there are three cobblers, and the top one is Zhuge Liang.

What's more, Xu Bin, Chen Jun, and Ouyang Chen are not stooges, but talented college students majoring in computer science.

If the three of them work together, it might really work wonders.

Xu Bin is a computer major, because he is very hobby and has good ability. In addition, during his more than one year in Wucheng University of Arts and Sciences, he also has the bonus of learning BUFF, as well as the various benefits given by Ding Yue. A small plug-in.

When Xu Bin faced the difficulties of the ACM competition, he did not say that he had no absolute certainty, but he did not have any confidence.

However, unlike Xu Bin, the participating students from several other colleges and universities were a little depressed.

They didn't have much pressure to solve the first five questions, and at most the fourth question took more time.

But for this sixth question, some students have even begun to feel a little frustrated.

"I don't think we can do it in an hour!" sighed Wilke of the University of California, Berkeley.

"Hey Wilke, let's get our confidence up!" encouraged Wilke's teammates.

"But......"

It can be seen that even the participating teams from the University of California, Berkeley, are already on the verge of collapse.

This is currently the top ten colleges in the rankings!

One can imagine how desperate other colleges and universities, and even the second-tier college teams, were when faced with the sixth question.

At this point, mentality is very important.

Xu Bin, Chen Jun, and Ouyang Chen from Wucheng University of Arts and Sciences analyzed this [question G] in an orderly manner.

Finally, Xu Bin had an idea.

"Look, can you try to solve it this way?" Xu Bin asked Chen Jun and Ouyang Chen while operating.

The two of them took a serious look and were not quite sure, but they nodded and said in unison, "Director Xu, I think we can try it!"

"it is good!"

Xu Bin took a deep breath, thinking of the expectations of his good brother, principal Ding Yue, and gritted his teeth, and began to try to solve [question G].

Even if this method does not work, Xu Bin thought that there should be a chance to change the solution.

But this method must be tried.

On the side of the competition committee, in 31 minutes, they received the "answer sheet" submitted by Imperial College London.

However!

The result given by the jury team is - WA!

That means the answer is wrong!

According to the answering competition rules of the ACM competition, if the program submitted within the specified time does not run correctly, the program will be returned to the participating team, and the participating team can make revisions and submit the question again.

That is to say, all participating colleges and universities have the opportunity of conscious trial and error.

It is clear that Imperial College is betting that their first submission will pass.

Once it can be passed, it is estimated that it can lead by a large margin.

Because of this problem, if everyone feels that it can be solved, it will take at least 50 minutes.

beep!

"Imperial College submitted wrong answer!"

The competition committee returned to the procedures of Imperial College London, and the three contestants of Imperial College were immediately stunned.

"It's over."

"There are still twenty minutes left, let's try plan B?"

"That's all, hurry up."

After the three were frustrated, they quickly adjusted their status. If plan A ran incorrectly, only plan B could be executed.

Like Imperial College of Technology, Moscow State University also chooses the AB option for trial and error.

Almost exactly the same, after submitting the A plan of Moscow State University, it was rated as WA by the jury team!

It was then returned to Moscow State University, and they immediately started the B plan.

But time is running out, and plan B may not have the chance to be fully realized.

In fact, Xu Bin of Wucheng University of Arts and Sciences also implemented the same method as Imperial College and Moscow State University.

That is to try it first, and if it is wrong, try another solution.

But when Xu Bin was writing the program, he found that there seemed to be no problem with this idea. With the assistance of Chen Jun and Ouyang Chen on the side, Xu Bin now just wanted to make the current answering method perfect and perfect as soon as possible!

"Brother Yue, several colleges and universities have submitted programs, but they are all wrong. Is this trial and error? But how did I find out that Abin and the others did not intend to prepare for trial and error?"

Huang Youjie saw the difference and asked Ding Yue curiously.

"The best way to solve this problem is to use trial and error. If Abin and the others don't plan to use this method, then there is only one problem."

Ding Yue said, a smile suddenly appeared at the corner of his mouth.

"What's the problem?" Lao Huang asked impatiently.

"That's why Abin and the others have the confidence to solve [question G] directly at one time!"

During the 30 minutes to 45 minutes of problem-solving time, colleges and universities continued to submit answer sheets, but all the responses from the judges were - wrong answer!

That is to say, they used the method of trial and error in a short period of time, and they were basically wrong.

As a result, many colleges and universities have almost abandoned this question.

Because there are still twenty minutes or ten minutes left, it is almost impossible to run the program of the second scheme perfectly.

Of course, there are also some excellent college teams who are confident, such as Imperial College London and Haicheng Jiaotong University.

53 minutes.

Xu Bin finished typing the last line of code, and then looked at Chen Jun and Ouyang Chen.

The two nodded in unison.

Once this is submitted, it will be fine if it passes. If it does not pass, it will be a bit miserable, and it may even lose the chance to compete for the championship.

After all, if the program fails to be submitted, there are still seven minutes left, and it will be too late to switch to another way.

Seeing that the two of them had firm eyes, Xu Bin felt a sigh of relief in his heart!

submit!

About half a minute passed.

beep!

"Congratulations to Wucheng University of Arts and Sciences for successfully solving [Problem G] in 53 minutes!"

boom!

With the purple balloon rising from behind Xu Bin, Chen Jun and Ouyang Chen, the first university to solve the sixth problem was born.

Wucheng University of Arts and Sciences!

The audience even burst into applause.

Because it has been 53 minutes, finally the first university successfully solved [Question G].

You can see that this question is really difficult.

Among the thirty or so colleges and universities, at least ten or so have given up.

There are also ten or so college teams who feel that they are too late.

Some of the rest are trial and miss, and the second time, and some are like Wucheng University of Arts and Sciences.

beep!

"Caltech successfully passed [question G] in seconds!"

In fifty-five minutes, Caltech also solved this huge problem.

In the next five minutes, Imperial College submitted the second answer sheet, which also passed, and Haicheng Jiaotong University passed in 58 minutes.

St Petersburg State University also passed in 59 minutes.

Answer sheet submitted by Moscow State University - wrong!

It's all right now, Moscow State University is directly cool, and I didn't get the score for this sixth question.

Nanyang Technological University actually passed the [question F] on the timeline.

The sixth question directly kicked other participating universities out of the championship competition.

In other words, champions can basically only be born from Wucheng University of Arts and Sciences, Imperial College London, St. Petersburg State University, Haicheng Jiaotong University, Caltech University, and Nanyang Technological University.

However, Nanyang Technological University's previous cumulative time results are relatively poor, so it is not generally difficult to compete for the championship.

At this moment, Ding Yue's heart was already in his throat.

The last question will decide the winner!

The competition committee announced the seventh question!

The difficulty of the seventh question, after the other college teams met, they were not interested in solving the problem.

Because of this difficulty, it is even more difficult than the sixth question.

If this program can be completed, I am afraid that there is no problem in any computer company in the world as the chief engineer of computer programs, right?

The three contestants from Haicheng Jiaotong University had the same expressions on their faces after seeing the seventh question.

"Gan! This... Although it took an hour and a half, how could this be done?"

"Nima, give me a month, I may not be able to solve it."

"This year's ACM competition topic is too BT, isn't it?"

The three young lads were a little desperate.

After a while, one of them calmed down and said, "Maybe there are other shortcuts to solve this program, otherwise, how could the competition committee let us take an hour and a half to solve this program that the team can solve in a month. program!"

"Makes sense!"

On the side of Wucheng University of Arts and Sciences, Xu Bin, Chen Jun, and Ouyang Chen were analyzing this question.

[Question G] It is really super difficult.

After seeing this, Ouyang Chen was dumbfounded.

Chen Jun is a little better, and he can barely analyze it.

Xu Bin frowned, because he also felt that this problem seemed unlikely to be completed.

But if you think about it, it shouldn't be.

How could the competition committee come up with a question that almost no one can complete?

"Have it!"

At this moment, the idea of ​​genius is always different from others.

"Director Xu, do you have an idea?" Chen Jun widened his eyes and asked Xu Bin.

At this moment.

On the St. Petersburg State University side, the three players were calm.

The three players from Imperial College London were having a heated discussion.

These players are called geniuses. In fact, they don't come to participate in the ACM competition. With their grades in school, they can easily go to work in any top computer company in the world.

Even among them there is no shortage of masters in the hacker circle.

For example, a player from Imperial College London is a master in the global hacking world, code-named "Mediterranean".

The game scene fell into silence for a long time.

Because the seventh problem solving time is as long as one and a half hours.

In the first hour, none of the participating college teams submitted an answer sheet.

One hour and twenty minutes.

Still not!

At one hour and twenty-two minutes, there was finally movement on the field!

beep!

"Congratulations......"

When Ding Yue heard the words congratulations, his pupils suddenly tightened.

Because he knows that the college team that solves the seventh problem is born, and the champion is very likely to be born like this!
