Chapter 76 Space Station Operating System
In the background of the data center, many hired expert judges are chatting.
Everyone's topics basically focus on one thing.
Li Chengqian's perfect score in the theory test.
"You say, will Li Chengqian be the first to hand in the actual programming test this time?" Shi Chengsan, who just corrected Li Chengqian's theory 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 difficult. You must convert the meaning of the questions into mathematical problems before you can program." A judge teacher guessed.
His meaning is obvious, Li Chengqian's programming ability and theory, he believes that there is no problem.
However, no matter how good the programming ability is, there is a prerequisite, that is, the problem needs to be converted into a mathematical model.
"Ding Dong, you have received a new test paper to be reviewed..." At this moment, the computer in front of Shi Chengsan sounded a reminder.
"Look quickly, who has 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 turned on the marking system and glanced at the names of the submitters.
The 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, 30 points for mathematical modeling and 70 points for programming ability.
"Old Shi, let's take a look at his mathematical modeling first." Amidst the commotion, Li Chengqian's simple mathematical derivation process was displayed in front of everyone.
"Hiss... amazing!"
"With just five formulas, the problem can be modeled. In Li Chengqian's team, there are not only programming experts like Li Chengqian, but also mathematics experts."
"Awesome... I see that the standard answer derivation is a full three pages of A4 paper. The derivation process of Li Chengqian's team is not even half a page, but they have explained all the questions clearly." To be honest, if I hadn't read the standard answer in advance , they may not be able to understand the derivation process written by Li Chengqian.
"Full score, full score for mathematical modeling!" Shi Chengsan filled in 30 points in the place of the score value and chose to submit it.
Then he opened the control software written by Li Chengqian.
After the code is downloaded, the neat 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 were filled with extreme shock.
Because the software written by Li Chengqian completely exceeded their expectations.
To make an inappropriate analogy, the question asks to calculate what 1+1 is equal to. This is a question for elementary school students. The answer given by Li Chengqian is to prove that 1+1=2, which is what mathematicians have to do.
This is not at the level of a high school student at all, it is simply the programming level of a doctoral supervisor of programming majors, even one level higher than that of a doctoral supervisor.
"The code has 1350 lines, and the software size is 65Kb!"
"The software has 1 core module and 5 functional modules."
"The software has an operating core, which provides a virtual hardware system. You only need to integrate the drivers of related devices into the software, and this software can run directly on the space station."
"Five functional modules, flight attitude control, automatic flight height and speed control, safe flight control, and a real-time display system that can display real-time speed, altitude, remaining fuel and other related information."
"All functional modules can be used normally, no bugs found!"
"This is an advanced and incomplete space station operating system!"
"Li Chengqian's practical programming, full marks!" In the end, Shi Chengsan directly filled in the scoring 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 Studies 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 after a slight modification, no matter 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 up immediately. This source code is too important and advanced, and must not be leaked. The competition organizing committee should immediately report it to the Secrecy Bureau and let them keep it secret." In the past, the operating systems of space stations were all customized, and the cost of research and development was tens of millions.
Once the source code of Li Chengqian is leaked out, it will become the common operating system of the space station after simple modification.
This is an important technological breakthrough!
"I'll report to the relevant department immediately." In 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 staff that they could not leave the examination room and could only wait in the square. After that, Li Chengqian began to explain the problem-solving ideas to Ding Ling and Zhao Peng, as well as the usage of the five formulas he wrote down. .
"...This is the specific meaning of the five formulas, and it's actually not as difficult as you imagine." Li Chengqian explained the functions of the five formulas to the two of them in detail.
Zhao Peng listened with a dazed expression, but still didn't understand.
Ding Ling looked thoughtful, holding the five formulas written by Li Chengqian, and thinking again.
"Captain, why don't you let us leave the big data center?" Zhao Peng glanced at the gate of the data center. The gate was tightly locked, and two security guards guarded the gate tightly, preventing anyone from entering or exiting.
Zhao Peng has already turned around and found that all the entrances and exits of the big data center have been controlled, and all entrances and exits are not allowed to enter or exit.
"I don't know either." Li Chengqian was also at a loss.
"Dingling... The practical programming exam for the Youth Informatics Programming Contest is over. Please leave your seats and leave the exam room." At this moment, the announcement that the exam was over rang.
"Let's go, let's go, they have no reason to hold us this time." After hearing the voice, Zhao Peng suddenly became excited and ran to the door to go out.
At this moment, He Hongyun, Bi Jialiang and Jian Qingli walked to the square.
He Hongyun's face was full of pride. Although the exam questions were difficult, he finally won them. The transformed mathematical model is the change of the height of the space station. It is necessary to change the flight speed of the space station to change the centripetal force, so that the centripetal force and The gravitational force of the earth is balanced, so as to achieve the purpose of stable flight of the space station.
After completing the mathematical model, Bi Jialiang worked with him. In addition to writing the core control code, he also wrote a data display program that can display the altitude and speed of the space station.
"Bi Jialiang's practical programming level is still good. If he majored in programming at university, he can be recruited to my father's company as a programmer after graduation." He Hongyun never saw Bi Jialiang in his eyes at all. What happened just now changed his mind, and he felt that Bi Jialiang was a talent that could be used.
"This actual programming test, our team's score is at least 90 points!" He Hongyun was absolutely confident, and then he saw Li Chengqian standing in the square.
The smile on his face became more and more smug.
"Li Chengqian's grades in textbooks are very good. There should be no problem in converting the topic into a mathematical model." He Hongyun 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 0 actual combat experience, and he was still learning to type a few days ago, and his typing speed is extremely slow."
"During the competition, I have Bi Jialiang on my side who can help me, and only Jian Qingli is the only one who can help me."
"On Li Chengqian's side, Zhao Peng and Ding Ling are two oil bottles. They can't help him at all."
"It's not bad that Li Chengqian can convert the core height and speed into part of the program. He doesn't even think about the others."
"So, in this practical programming test, I can definitely beat Li Chengqian." Thinking of this, He Hongyun couldn't help laughing.
