In the background of the data center, many hired expert judges are chatting.

Everyone's topics basically focused on one thing.

The story of Li Chengqian’s perfect score in the theoretical examination.

"Do you think Li Chengqian will be the first to hand in the practical programming test this time?" Shi Chengsan, who happened to be correcting Li Chengqian's theoretical test paper in the morning, joked.

"It's hard to say. Li Chengqian's theoretical foundation is very good, and his programming ability is not to mention, but the questions on this space station are very difficult. You must convert the meaning of the questions into mathematical problems before you can program." One of the judges teacher guessed.

His meaning was obvious. He believed that Li Chengqian's programming ability and theory would be no problem.

However, no matter how good your programming skills are, there is a prerequisite, that is, you need to convert the problem into a mathematical model first.

"Ding dong, you have received a new test paper to be reviewed..." At this moment, the computer in front of Shi Chengsan sounded a prompt.

"Look who handed in the paper, see if it's Li Chengqian." Someone booed, and then many people gathered around and stood behind Shi Chengsan.

Shi Chengsan opened the grading system and took a look at the name of the person who submitted the test.

The three words Li Chengqian came into his eyes.

"It's really Li Chengqian!" someone said in surprise.

In the marking system, this exam is divided into two parts, mathematical modeling with 30 points and programming ability with 70 points.

"Lao Shi, let's take a look at his mathematical modeling first." Amid the commotion, Li Chengqian's simple mathematical derivation process was displayed in front of everyone.

"Hiss...that's awesome!"

"With just five formulas, the problem is modeled. In Li Chengqian's team, there are not only programming masters like Li Chengqian, but also math masters."

"Awesome... I deduced the standard answers on three pages of A4 paper. The derivation process of Li Chengqian's team did not take half a page, but they explained all the questions clearly." To be honest, if I hadn't read the standards in advance,

The answer is that they may not be able to understand the derivation process written by Li Chengqian.

"Full marks, full marks for mathematical modeling!" Shi Chengsan filled in 30 points in the score field and chose to submit.

Then he opened the control software written by Li Chengqian.

After the code is downloaded, the clean and standardized code is displayed in front of everyone, whether it is indentation or comments, it is like a textbook.

As the test progressed, everyone's faces showed extreme shock.

Because the software written by Li Chengqian completely exceeded their expectations.

To use an inappropriate metaphor, the question requires calculating how much 11 equals. This is a question for primary school students. The answer given by Li Chengqian is to prove that 11=2, which is what mathematicians have to do.

This is not the level of a high school student at all, it is simply the programming level of a doctoral supervisor in programming, even one level higher than that of a doctoral supervisor.

"There are 1350 lines of code and the software size is 65kb!"

"The software has 1 core module and 5 functional modules."

"The software has an operating core. The operating core provides a virtual hardware system. You only need to integrate the drivers of relevant devices into the software, and the software can run directly on the space station."

"Five functional modules, flight attitude control, automatic flight altitude and speed control, safety flight control, and stone chamber display system, which can display real-time speed, altitude, remaining fuel and other related information."

"All functional modules can be used normally, and no bugs have been found!"

"This is not a software!"

"This is an advanced space station operating system that is not yet perfect!"

"Li Chengqian's practical programming, full marks!" In the end, Shi Chengsan directly filled in the score column with 70 points.

"I suggest that the organizing committee of the competition submit the space station operating program written by Li Chengqian to the Institute of Space Affairs of the National Academy of Sciences." The space station operating system written by Li Chengqian can not only be used on the space station, but with slight modifications, whether it is a space shuttle,

Satellites can use this code as an operating system.

"I suggest that Li Chengqian's software and source code be sealed immediately. This source code is too important and very advanced and must not be leaked. The competition organizing committee should report it to the Secrecy Bureau immediately, and the organizing committee will handle it confidentially.

." In the past, space station operating systems were specially customized and cost tens of millions in research and development.

Once Li Chengqian's source code is leaked, it will become a universal operating system for the space station with only simple modifications.

This is an important technological breakthrough!

"I will report to the relevant departments immediately." During this competition, Chen Lili, the person in charge of Jinshan Province, became extremely serious after hearing the report from her subordinates, and hurried to the Secrecy Bureau.

…

In the big data center square, Li Chengqian and others were told by the examination administrator that they could not leave the examination room and could only wait in the square. After that, Li Chengqian began to explain to Ding Ling and Zhao Peng his problem-solving ideas and the use of the five formulas he had written down.

.

"...This is the specific meaning of the five formulas. In fact, it is not as difficult as you think." Li Chengqian explained the functions of the five formulas to the two of them in detail.

Zhao Peng listened with a confused face, still not understanding.

Ding Ling looked thoughtful, took the five formulas written by Li Chengqian, and started thinking again.

"Captain, why don't you let us leave the big data center?" Zhao Peng glanced at the door of the data center. The door was locked tightly, and two security guards guarded the door to prevent anyone from entering or exiting.

Zhao Peng had already gone around and found that all the entrances and exits of the big data center were controlled, and no entry or exit was allowed at all entrances and exits.

"I don't know either." Li Chengqian was also confused.

"Ding ding bell... The practical programming test of the Youth Informatics Programming Competition is over. Please get out of your seats and leave the examination room." At this moment, the announcement of the end of the test rang.

"Let's go, let's go, they have no reason to stop us this time." After hearing the sound, Zhao Peng suddenly became excited and ran to the door to get out.

At this time, Stanley Ho, Bi Jialiang and Jian Qingli walked to the square.

Stanley Ho had a proud look on his face. Although the test questions were difficult, he was finally able to win. The mathematical model he transformed was a change in the height of the space station, which would inevitably change the flight speed of the space station and thereby change the centripetal force, so that the centripetal force and

The earth's gravity is balanced to achieve the purpose of stable flight of the space station.

After completing the mathematical model, Pi Jialiang worked with him. In addition to writing the core control code, he also wrote a data display program that can display the height and speed of the space station.

"Bi Jialiang's practical programming level is still acceptable. If he studies programming in college, he can be recruited to my father's company to be a programmer." Stanley Ho had never seen Bi Jialiang in his eyes in the past. What happened just now changed.

After hearing his thoughts, he felt that Pi Jialiang was a talent that could be used.

"Our team's score in this practical programming test is at least 90 points!" Stanley Ho was absolutely confident. Then, he saw Li Chengqian and others standing in the square.

The smile on his face became more and more proud.

"Li Chengqian's textbook scores are very good. There should be no problem in converting the questions into mathematical models." Stanley Ho is not a fool. Although he is particularly unhappy with Li Chengqian, he still has basic judgment skills.

"I heard from Bi Jialiang and Jian Qingli that Li Chengqian has zero practical experience. He was still learning to type a few days ago and his typing speed was extremely slow."

"During the competition, I have Bi Jialiang here who can help me. Only Jian Qingli is a drag."

"On Li Chengqian's side, Zhao Peng and Ding Ling are two weaklings. They can't help him at all."

"It would be great if Li Chengqian could complete part of the most core height and speed conversion procedures. He can't even think about the rest."
Chapter completed!
