Top Student: Experience Infinite Occupations

75 Difficult Question

“F*ck, what kind of a question is this?” Looking at the question on the big screen, Zhao Peng was dumbfounded.

Ding Ling also frowned as she looked at the question on the big screen. If she was given enough time, she might be able to come up with a solution to the problem, but it was basically impossible to do so within such a short period of time.

“Actually, this question isn’t too difficult…” Li Chengqian looked at the question. After thinking carefully for a while, he already had an idea in his head.

The question was set out on the big screen.

You are the software developer of a space station. It is currently known that the space station will orbit around the Earth at the same time. There are a total of eight rocket thrusters on the space station. Please develop a Positional Control program for the space station to ensure that it can orbit steadily in a geosynchronous orbit. (Requirement: The ground command center can adjust the space station’s operating height based on situational requirements.)

After this question appeared on the big screen, all the students participating in this competition looked at the big screen in confusion.

“This is sick! How can there be such a question? Does anyone know what the altitude of a geosynchronous orbit is?”

“D*mn, they are just trying to fail us in this hands-on programming segment?” Someone almost cried. He could understand every word in this question, but he had no clue when it was converted into a mathematical model.

Over at Bi Jialiang’s team, He Hongyun looked at the question and fell into deep thought. This question was really tough.

Jian Qingli looked at Bi Jialiang feebly. She realized that Bi Jialiang was also frowning tightly. He was holding a pen in his hand. The draft paper was still blank. Clearly, he had no clue about this problem.

“Is this question really something that high school students can do?” Jian Qingli looked at the question and fell into self-doubt.

In Li Chengqian’s team, Li Chengqian picked up a pen and wrote the gravitational formula on the paper.

“This problem is actually not as complicated as I thought. Let’s assume that the space station’s mass is M and the altitude from the ground is H. We can calculate the Earth’s gravitational force on the satellite, set the velocity to V, and calculate it through the centripetal force calculation formula…” Li Chengqian wrote the steps of the analysis on paper.

Five sentences and five formulas.

He turned the question into a mathematical model.

“Captain, you’re a genius! What brain food did you grow up on?” Zhao Peng looked at the formulas and analysis on the paper. He had both shock and admiration on his face.

Ding Ling frowned and looked at it again and again. She realized that she still couldn’t understand what Li Chengqian had written. She looked at Zhao Peng suspiciously and couldn’t help but ask, “Zhao Peng, you understand the derivation process?”

“I don’t understand!” Zhao Peng replied matter-of-factly. “Can an ordinary person like me understand such a complicated thing? You overestimate me.”

“If you don’t understand, why are you acting so shocked?” Ding Ling was almost dumbfounded by Zhao Peng’s response. If one didn’t know better, they would definitely think that Zhao Peng had understood.

“The captain is so awesome. Isn’t it something worth marveling at?” Zhao Peng looked at Ding Ling with a puzzled gaze.

“…” Ding Ling shook her head speechlessly and stopped paying any attention to Zhao Peng. She looked at Li Chengqian’s analysis on the paper carefully and focused on thinking.

Li Chengqian’s hands were on the keyboard. He didn’t even need to think and directly typed lines of code into the computer.

“Because the transmission speed of the Star Earth network is very slow, the Positional Control program has to be light.” Even hard disks have to be specially tailor made for the space station. Its capacity was extremely small but its price was astronomical. A special hard disk of 500 gigabytes cost 800,000 yuan!

“A program running on the space station must have high performance.” The same principles applied to CPUs that could function in space. Stability came first. The performance was not high, but the price was terrifyingly high.

“It’s a critical program because it’s a Positional Control program that controls the space station. There is no room for errors. After the software receives the signal from the outside world, it has to start operating immediately. The response speed of the program has to reach the millisecond level.”

“For the safety of the space station, the range of the space station’s altitude from the ground is…” If it was too low to the ground, it might crash. If it was too high, it would leave Earth’s gravity and fly into outer space.

This was a relatively complicated project, and there were many things to consider. These questions were divided into small functional modules by Li Chengqian.

Li Chengqian’s fingers danced on the keyboard at the speed of 15 lines of code per minute.

Crackling sounds rang out densely, filling the entire space.

After an hour and a half, Li Chengqian’s hands finally stopped.

[Real-time space station altitude and speed adjustment subsystem 100% complete. Software grade D-.

[Space station altitude and speed safety subsystem 100% complete. Software grade D-.]

This module would allow the space station to adjust its altitude while flying steadily in the air.

[Real-time space station flight mode adjustment subsystem 100% complete. Software level D-.]

This module could adjust the mode of the space station. It could fly horizontally, vertically, diagonally, or even roll. This software could accurately adjust the direction of the space station.

Li Chengqian didn’t do this to kill time. He did this because the space shuttle needed to dock at the space station, so the space station flight mode adjustment software was really essential.

[Space station operating system completion rate 23%.]

“Done!” Li Chengqian smiled when he saw the system notification.

He thought to himself, “Compared to developing the Divine Dragon Operating System core, it’s not that hard to develop the space station operating system.”

“If you give me the specific hardware parameters of the space station, it won’t take me much effort to develop the operating system of the space station.”

“However, the feeling of manually inputting the codes cannot be compared to the feeling of using the Mental Coding skill.” He was used to the input speed of 3,000 lines of code per minute. He was really not used to the old speed of 15 lines of code per minute. This was 200 times the difference in efficiency.

“I must get the brainwave receiver done!” Li Chengqian resolved again.

Meanwhile, Ding Ling was dumbfounded. She had both shock and admiration in her eyes. This was the first time she had seen Li Chengqian type. Li Chengqian’s fingers were like phantoms. At the same time, the words that appeared on the computer were so fast that she almost couldn’t read them.

“How can Li Chengqian’s typing speed be so fast! It’s amazing! Unbelievable!” Ding Ling looked at Li Chengqian with admiration and shock in her eyes.

Zhao Peng had long been used to Li Chengqian’s typing speed. Seeing Li Chengqian stop, he excitedly rushed to Li Chengqian’s side. “Captain, is it already done?”

“Yes, it’s done! I need to test it now.”

Right on the heels of that, Li Chengqian used the programming software to test and confirmed that the program was running smoothly without any bugs.

Li Chengqian tried to input the relevant parameters such as the height of the space station, the power of the rocket engine, the amount of fuel, the weight of the space station, and so on to simulate the operation.

On the simulation interface, data such as the time needed to adjust the height, the amount of fuel required, and the operating speed of the adjusted space station were displayed.

If it was really operating on the space station, it could also show the real-time speed, real-time altitude, and other relevant data of the space station.

After seeing that there were no problems with the test, Li Chengqian uploaded the mathematical deduction process formula, as well as the software code. This completed his submission.

“This time, it should also be full marks!” The program he had written only needed simple improvements to be used on the real space station, and it was especially useful.

As long as it was someone who understood the industry, they would definitely give him full marks.
