Just turned over a new leaf and became a wise and intelligent student

Chapter 252 No, he is sick! (3.5 in 1)

"Yang Shu, you really need to rest well these two days and don't mess around."

After a small gathering in the hotel in the evening, Xu Qingshan solemnly gave Yang Shu some instructions before returning to the room. It seemed that the boy did not have a good rest in the afternoon. He was still holding his laptop and writing code during dinner.

"Well, I know."

Yang Shu answered honestly, then walked towards the hotel room holding his computer and writing code.

"I don't know if this kid really listens to advice."

Xu Qingshan shook his head helplessly.

Mei Hong was still socializing on the campus of East China University, but Chen Dayue came back and brought some cakes for Xu Qingshan and the others. He seemed familiar with the place and had obviously been to Shanghai on business trips many times.

Xu Qingshan was not in a hurry to talk to Chen Dayue about the twin prime conjecture.

The results of such an important issue naturally need to be verified multiple times, repeatedly looking for loopholes, and then finding the right time to publish.

Right now we should focus on the game.

The next day.

Led by Mei Hong, the three representative teams of Peking University went to the hall to attend the opening ceremony. After a short meeting, they entered the gymnasium of East China University for a warm-up match.

The layout of the ICPC competition venue was even more informal than Xu Qingshan had imagined.

The competition he imagined was like a private room in an Internet cafe, with each team in a classroom and all communicating via computers, with everyone communicating with each other in a very high-end way using sharp eyes.

The technological style of future IT elites was fully demonstrated through constant communication.

Or it could be the kind of competition where everyone works together on the same stage to carry out network security offense and defense on a high-end all-in-one platform, and then the camera lens is aimed at each team member to give a good display.

But the actual ICPC competition venue is a very plain-looking gymnasium.

The red carpet on the ground is actually long red cloth that is spliced ​​together. Each piece of red cloth needs to be sealed with many layers of plastic tape and glued to the wooden floor of the gymnasium.

The table was also made of thin boards, and Xu Qingshan had no doubt that he could punch through it with one punch.

The computer was provided by East China University.

However, Xu Qingshan felt that it was not easy for them to move hundreds of computers into the gymnasium, especially these bulky old computers.

During the warm-up match, there were many volunteers cheering nearby wearing various kinds of clothes and small red vests, checking for missing pieces. One of them was carrying a large bag of balloon skins and blowing them up with his cheeks puffed out.

For a stadium this big, naturally there is no need for things like air conditioning.

There were slides playing on the big screen in the middle of the gymnasium, and the operating table next to it was also cluttered with equipment and cables, making it look like a makeshift team.

Not to mention that after entering, the entire gymnasium was in chaos and very noisy.

If you don't speak loudly, you won't be able to hear what your teammates are saying. If you want to communicate well, you basically need to lower your head and talk loudly together.

“I didn’t expect it to be so noisy during the game.”

Xu Qingshan complained helplessly to Jiang Huanxi beside him.

"What did you say?"

"I said! I didn't expect it to be so noisy during the game!"

"Oh, don't be so loud, I can hear you."

"Check your student ID and ID card again. Don't drop them here."

"Okay, I brought a math manual and an English-Chinese dictionary."

"Why did you bring that?"

Xu Qingshan watched Jiang Huanxi take out two large books from her bag and show them to him.

"I found on the Internet that it is used to ward off evil spirits and as a lucky charm."

"It's okay. You are our greatest mascot to ward off evil."

On the other side, Yang Shu had already started the computer.

There will also be rankings and duration records for the warm-up matches, but they will not be included in the results. The main task of the warm-up matches is to allow the participating teams to test whether there are any glitches in the system and computers.

"Yang Shu, is the test finished?"

"The template is OK, the table formula is normal, the Java input and output are normal, and the vim custom configuration is OK."

Yang Shu was operating the computer and reporting loudly to Xu Qingshan.

Although he is indeed socially anxious, when he sits in front of the computer and starts working, he forgets about it.

Xu Qingshan suddenly felt a little tired of taking care of two socially anxious people in this kind of situation.

Fortunately, after Jiang Huanxi's gradual training, he is now much better at handling lively situations.

"The operating system is the latest version of Ubuntu, ok."

"Recheck the configuration thoroughly. If you use an IDE, CodeBlocks is for C++, Eclipse is for Java, and there should be NetBeans. If you use an editor, the configuration of Vim should be written under ~/.vimrc. Emacs should have it, but GVIM may not. You should pay special attention to this later. Huanxi and I will go to the side to check the location of the balloon, board, and toilet. You can test the machine again."

"it is good!"

Yang Shu didn't even turn his head.

Xu Qingshan took Jiang Huanxi to check out the stadium and find the locations of toilets and other key event service points to avoid wasting unnecessary time.

"JAVA big numbers, main class name print JAVA.math to see"

"Ask MLE, test numerical limits. After testing PERE, will it return WA or RE?"

“Try STL-vector, string, map, set in advance to see if they can be used.”

Yang Shu was muttering something that ordinary people might not understand.

The mysterious look is very common in the conference hall.

By the time Xu Qingshan and the others came back, Yang Shu had already completed the test.

"Qingshan, it's okay."

"OK, do a few questions to warm up first. I'll watch you for a while. Xiaoxi has printed out the templates for the parts you are good at. When the time comes, we can divide the work of reading and typing the questions. When you encounter mathematical problems, let Xiaoxi solve them. If you want to grab the keyboard, we can set some rules ourselves."

"Okay, you're the captain, I'll listen to you."

"When the time comes, you will get the balloons if you answer correctly. Xiaoxi will handle all other questions. She will handle things reliably and I trust her."

"it is good."

When Xu Qingshan became the team leader, he naturally showed a talent for organization.

Although at this time there were only two people who followed his command.

But Yang Shu admired Xu Qingshan and naturally cooperated.

Not to mention Jiang Huanxi.

"Come on, let's start practicing!"

These three young people who had no experience in ICPC competition sat in front of the computer and started working.

Although it was his first time participating, he seemed to be able to handle it with ease, without the confusion and lag that is common among newcomers.

On the other hand, several other teams that were considered strong contenders for the first place in the competition had only one person doing the test, while the others were chatting and analyzing the strengths and weaknesses of other teams.

Jin Bin, a member of the team from Shanghai Jiao Tong University, is testing equipment.

Captain Zheng Zhao and his teammate Wu Zhuojie were observing the other teams in the arena. Zheng Zhao crossed his arms over his chest, acting like a big boss, and spoke to Wu Zhuojie beside him.

"Brother Jie, which teams do you think are stronger in this competition?"

"Well, I think it's Huaqing's."

Wu Zhuojie pushed up his glasses.

Wearing glasses, he looks very calm.

"Huaqing should still be led by coaches Wu Xiaojun and Wu Wenhu this time. Wang Dong, Tang Wenbin, and Long Fan are not weak. Two years ago, when they were sophomores, they won the silver medal in the finals. Now they are seniors, and they are probably aiming for the gold medal this time."

"There is also the NO.001 team from Beijing University that suddenly emerged. It is said to be composed of three freshmen from Beijing University, but there is a guy who is extremely good at mathematics. He is Xu Qingshan. Do you know him?"

"As for the teams from abroad, there are quite a few strong ones in the European and North American regions, but in the Asian region, there are only National Taiwan University, Aurora University, Zhongshan University, and Hong Kong Chinese University. You can pay attention to them. Oh, and there is also a younger team, China University of Science and Technology. But their goal should only be to win a medal, which does not conflict with our goal."

Zheng Zhao nodded.

He just looked around the venue carefully and didn't see the two teams that Wu Zhijie just mentioned.

But in his opinion, neither the Huaqing team, which won the silver medal in the previous competition and the silver medal in the previous competition, nor the dark horse Beijing University Xu Qingshan team, would give up this game in the Shanghai division.

"Then when I go to look at the scoreboard, I will focus on Huaqing and Beijing University."

Zheng Zhao said.

"It's okay. The three of us have our own strengths and are the best combination. Brother Jie, you are calm and have comprehensive skills, and Xiaobin is very fast at writing code. When the time comes, you will be the one to handle the complex and lengthy code, and Xiaobin will be the one to handle the template questions that require speed. I will assign the tasks, make decisions, and arrange the solution ideas."

Zheng Zhao is the backbone of this team.

His face was full of confidence.

"The glory of the Shanghai Stock Exchange is up to us. We are not here just to win medals. Our goal is to be the world's number one!"

Zheng Zhao is very confident.

Because their team has poured in more than just the hard work of the three of them, the school has also provided a lot of convenient resources and guidance from elite backbones.

We even invited seniors who had won the 26th and 29th global championships at the Shanghai Jiao Tong University to come back and provide guidance.

Among them, Lin Chenxi, a member of the 26th championship team, has already joined Alibaba and been promoted to P9. His promotion speed is ridiculously fast.

They came here this time just to win the championship!

"The test is over, what are you guys talking about?"

Jin Bin popped out from behind and asked curiously.

Zheng Zhao repeated Wu Zhijie's analysis just now.

"Harmful!"

Jin Bin waved his hand indifferently.

"What's that?"

"I think Huaqing is nothing but a pile of dry bones in a tomb, and Peking University is even less than a pile of dirt!"

Jin Bin has watched a lot of Romance of the Three Kingdoms recently, so he can talk about it fluently.

"Xiao Bin, don't talk nonsense. Huaqing has always been strong and is guaranteed to win the silver medal. Xu Qingshan from Jingda is definitely not a student of our level this time."

Wu Zhijie said seriously.

"Brother Jie, what are you doing~"

Jin Bin was grinning.

"Hua Qing is not weak, but it is only of silver quality. Do they not want to win the gold medal? It's because their strength doesn't allow it!"

"And Beijing University, Xu Qingshan is strong, but he is good at mathematics? What does that have to do with us writing code? Can the academicians from the School of Mathematics come here and crush our students from the School of Computer Science? That's hard to say. In my opinion, we are bound to win the championship this year!"

"Okay, don't be so confident."

Zheng Zhao said, crossing his arms.

“We just need to pursue our limits.”

"Come on, warm up, practice your coordination, and give these young people a little Shanghai shock."

Zheng Zhao rubbed his wrist and signaled Jin Bin to return to his position. They were about to begin to seriously test the results of their team's coordination.

The ICPC competition venue was bustling with activity.

Many people also want to make a good impression and have good luck in the warm-up matches.

The scoreboard in the center of the stadium also has a real-time updated ranking of the number of questions answered.

It didn't take much time.

The name of Shanghai Jiaotong University's Zheng Zhao's team appeared at the top of the list, far ahead.

By around noon, Zheng Zhao and his team had worked together to answer 4 questions perfectly, which took only 2 hours. Most of the other teams had only solved 1 or 2 questions, and some teams had not even solved any questions at all.

"That's all. I took a look and found that the two teams from Huaqing had just solved the third problem. No. 001 wasn't even in the top 12 on the first page of the list. Captain Zheng, aren't you being too cautious? I always say that math students don't understand computers."

"We should not take it lightly, otherwise why are they ranked first in the online qualifiers?"

Zheng Zhao shook his head and gave the arrogant Jin Bin a slap.

"Let's go, let's go eat. After dinner, come back and test for a while. Have a good rest tonight. Don't make any mistakes tomorrow."

Zheng Zhao took Wu Zhijie and Jin Bin away from the table and walked to the middle of the gymnasium. He saw a few relatively empty seats. It was obvious that the team members had gone to eat. He casually glanced around and saw the seats of Xu Qingshan and the others.

Empty.

Shaking his head, Zheng Zhao felt that he was being too cautious.

The noise in the stadium during the first day's warm-up match did not continue in the official match on the second day.

Because the first day is more about raising questions and solving problems.

The makeshift venue did indeed raise many issues that needed to be discussed and resolved.

But on game day, everyone was noticeably quieter.

Although there was some noise due to the limited capacity of the stadium and so many people in it, the main noise came from the contestants' inaudible discussions and keyboard typing.

Due to the issue of event arrangement.

The scoreboard will start to refresh the ranking records at 12 noon.

In the first two hours, there was no way to clearly know how many questions each team had answered. If you wanted to find out, you had to run to other people's tables and count how many balloons there were.

Because according to the rules of the competition.

After each team correctly completes a question, the organizer will raise a balloon representing the color of the question in their position. The first team to solve each question will also receive an additional "FIRST PROBLEM SOLVED" balloon. But when everyone is busy answering questions, especially when most teams are similar to the low-profile version of the Shanghai Jiao Tong team, there is no way to spare people to see how many balloons other teams have.

But for the team near the No. 001 of the Beijing University representative team, their hands were shaking almost when they were typing on the keyboard.

No?

Is he sick?

Is that how you play?
Didn’t your mother tell you not to bully other children when you are outside?
Didn’t your mother tell you to leave some room for error so that you can meet again in the future?

They felt a little uncomfortable as to why they were assigned a seat next to Kyoto University.

They were actually quite happy when they saw Xu Qingshan yesterday. After all, he was considered a top celebrity among college students. Some people even took cameras to take photos with Xu Qingshan.

But today they were not happy at all.

Because at this moment, there were 001 balloons floating next to NO.6's table.

That's right, 6.

Before 12 o'clock and the points board was opened, Xu Qingshan had already completed the codes for 4 questions and passed them all successfully in one go. He even received extra first-pass balloon rewards for the first two questions.

The reason why I didn’t get questions 3 and 4.

This is because during the competition, various teams often choose to start with other questions.

Xu Qingshan and his team’s third question might also be someone else’s first question.

But the shock and excitement that Xu Qingshan and his team brought to the people nearby was more than that.

Their team made quite a big noise.

Yang Shu solved the first problem, and Xu Qingshan would occasionally interject when Yang Shu got stuck. But when it came to the second problem, Xu Qingshan moved to the computer and started to work on the code himself.

When Xu Qingshan sat down at the beginning, the contestants next to him noticed him.

Only the players from the two teams that were not from mainland schools didn't know Xu Qingshan very well and had no feeling about him.

But after Xu Qingshan sat down.

His hands flew.

As we all know, the keyboard makes a sound when you type.

The sound frequency of the keyboard also represents the typing speed to some extent.

The computer keyboards of Xu Qingshan's team have not stopped making noises since Xu Qingshan sat down.

Crackling.

Ji Li Gua La.

There is no harm without comparison.

Same computer, same keyboard, same questions.

The keyboards in their hands are like constipation. They can't even defecate, and they are afraid of defecating in the wrong place and causing the toilet to be clogged.

The keyboard in Xu Qingshan's hand is like a piano, and he uses it to play the most exquisite musical melody.

what?
Are you questioning Xu Qingshan's random guessing?
Didn’t you see that after he sat down, on average every 25 minutes, the pretty and lovely girl would go to the balloon point of the organizing committee to get a balloon?

Can you show me a few random knocks?

In a team near Xu Qingshan's team, a girl looked up depressedly and spoke to the stunned teammates beside her.

"I'm a bit autistic. We can't write at all while sitting here."

"what?"

"Seeing how fast Xu Qingshan solved the problem, I couldn't help but wonder if there was something wrong with my IQ. Others could solve a problem in more than 20 minutes, but I couldn't figure it out after an hour. Sigh, let's move on to the next problem. You do it."

"Why do you think I can do it?"

"Didn't Xiaoyu go to the toilet? Tell her later."

"Explain what?"

"Give her a mission to kill Xu Qingshan."

Xu Qingshan naturally didn't know that his actions would cause such great interference to the surrounding teams.

Now he just feels that he is enjoying typing code.

Yang Shu and Jiang Huanxi sat on his left and right. Yang Shu felt itchy to do something while Jiang Huanxi felt itchy in his heart.

soon.

It's almost twelve o'clock.

Jiang Huanxi quickly got up and went to the cafeteria of East China University to get lunch boxes for them, while Xu Qingshan and Yang Shu continued to watch the computer.

"Come on, Lao Yang, you take over for a while. I've looked at questions 7 and 8. I'll think about it. You did question 6. These two are exactly what you're good at."

After Xu Qingshan solved the fifth question, he stood up and stretched, gave some instructions to Yang Shu, and went to the balloon point to get the balloons.

Xu Qingshan flexed his fingers.

He now has a better grasp of his limbs and can feel the comfortable force points, but he still can't stand the soreness caused by the stable high-speed code.

When we reached the balloon point, some people came to get the balloons. There were people in front and behind Xu Qingshan.

It seems that in the nearly 2-hour period, there are quite a few teams that successfully solve the problem.

"Hello, please show us your team badges."

The volunteer girl had a sweet smile, perhaps because she had a natural liking for a handsome programmer among a group of programmers.

Sometimes handsome guys become even more handsome when compared with ordinary people.

That's not an illusion, it's the result of human visual contrast processing.

It was as if the volunteer girl's heart was pounding. When she saw Xu Qingshan's face, which was so affectionate that even a dog could see it, she was stunned for a moment.

"Hello, can I check it?"

Xu Qingshan waved the team badge in his hand and asked.

I heard that in some competition zones, volunteer ladies delivered the food directly to the table. The Shanghai competition zone was really stingy and didn’t even hire more volunteer ladies.

Xu Qingshan saw the volunteer lady in front of him come back to her senses, her cheeks flushed, and she began to check the number of questions in the team, thinking to herself.

"I seem to remember your team's name. I've been here several times. How many problems have you solved so far?"

The volunteer lady subconsciously tried to find a topic to talk about.

"5 questions. This time I got the 5th question."

Xu Qingshan replied, rubbing his hands.

There were still a lot of people queuing behind him, but Jiang Huanxi was still buying food for him. He was chatting with the young lady here, feeling a little uncomfortable.

"Five questions? Ha. Man, it's fine to trick the ignorant young lady, but don't even bother with the competition. You'll end up tricking yourself later."

A young man who looked very energetic behind Xu Qingshan sneered, leaned over and laughed sarcastically.

Don't blame him.

He just couldn't stand other people showing off just to pick up girls.

Besides, he also thought that this volunteer girl was pretty nice and cute.

Everyone is in the Shanghai Stock Exchange, and Huadong is not far from the Shanghai Stock Exchange. He specifically asked the team leader for the job of getting balloons. He wanted to chat more with the young lady and ask for her QQ number later.

Hearing this, Xu Qingshan turned around and looked at the young man behind him.

Well, I don’t know.

He said "Oh" calmly, turned around and continued to wait for the balloon from the volunteer girl.

"Hey, what are you pretending to be?"

Jin Bin was a little annoyed.

Xu Qingshan's response seemed to be ignoring him, making him feel like a clown inexplicably.

"Shanghai Jiaotong University, two-time champion, understand?"

Jin Bin showed the team badge in his hand with a cocky and arrogant expression, looking down on Xu Qingshan. Xu Qingshan felt that he was very suitable to play the role of a young master in a film or TV series.

"Oh."

Xu Qingshan turned his head again, put his hands on the table and tapped them slowly and rhythmically.

"Oh, you are really pretending. I don't really want to expose you, but you are really not that good. It's not bad that you can solve the 5th question, but it's too much to lie and say that you can solve 5 questions. This is a dishonest behavior. Our team is so strong, and you have only solved 4 questions so far. You don't think I will really believe you, right?"

Xu Qingshan ignored the talkative young man behind him who was repeating the same words.

He gently tapped the balloon-dotted tabletop and asked.

"Hello, can I get the balloon now?"

"I'm talking to you!"

Jin Bin was furious.

The guy in front really disrespects him!
When has the man nicknamed "Little Genius Jin Ershao" ever suffered such humiliation?

Popularizing scientific knowledge and upholding justice, but being shamelessly ignored.

"It's okay."

The volunteer girl was also a little confused and handed the balloon in her hand to Xu Qingshan.

"You are so strong."

"Of course, our Shanghai Stock Exchange has won the championship twice, so we have the foundation."

"You've actually solved 5 problems. Look at the board at the back. It's been updated. You're ranked first!"

The volunteer girl's eyes were shining with little stars, but she was clearly looking at Xu Qingshan, not Jin Bin who was sticking his head out.

"Ok?"

Jin Bin was also confused.

His voice stopped and he subconsciously turned to look at the giant screen on the stage.

【NO.001, 5 questions.】

The names on the first row catch your eye.

He subconsciously turned around and looked at the team badge that Xu Qingshan had taken back from the volunteer girl. It also had [NO.001] written on it.

For a moment, Jin Bin felt that the world was very chaotic and confusing.

Xu Qingshan turned around and glanced at the young man who suddenly appeared behind him.

In fact, he was not angry.

Xu Qingshan held the balloon and the team badge in one hand, and with the other hand he simply patted the confused boy's shoulder and spoke earnestly.

"Don't worry, I'm not angry."

"After all, people can only see the limits of what they can do."

"This is my problem, not yours."

"But kid, you are still young. After you get the balloons, remember to go back to Gotham City to find Batman and continue the fight."

"The people of Gotham need you."

After saying that, Xu Qingshan turned around, smiled and waved to the volunteer girl, then walked back to his team.

Jin Bin stood in front of the balloon, thinking about Xu Qingshan's words.

"Hello, please show me your team badge."

"Oh, here you go."

A simple chance encounter.

Xu Qingshan successfully sank a capable general of the Shanghai Jiaotong Team.

Although he didn't mean to do so, the other person was young and aggressive, and he came to him to defeat her. It would be embarrassing if he didn't say something.

"What's wrong with you? Why are you so depressed after receiving a balloon?"

Zheng Zhao looked at Jin Bin who was in a daze in front of the computer.

"Captain Zheng, please look at the first one."

Jin Bin pointed to the giant screen.

Zheng Zhao and Wu Zhijie glanced at each other.

"Well, Xu Qingshan and his team are first, and we are second. What's wrong?"

"what?"

Jin Bin couldn't understand the captain and Brother Jie's calm attitude.

"This is just the qualifiers. Although we get first place directly, whether we get first place directly or not will not affect our entry into the finals."

Zheng Zhao said calmly and looked at Wu Zhijie.

"Xiao Bin, let me do it. Adjust your mentality."

Wu Zhijie asked Jin Bin to make way for him.

"Besides, the competition isn't over yet. This is just a one-question advantage. We won't know if it works until we try it."
