Reborn Ace Hack

Jessica's ugly face is so ugly that I don't know how to describe it in words. If this woman's face is regarded as a motherboard, and if the facial features can be removed from the face like computer components, individually, the quality is not bad, but it is

These high-quality components are placed on this face, but they look out of place. This feels weird.

Xiao Yuan only glanced at Jessica and felt very uncomfortable. Out of politeness, he resisted turning his face to one side and gave her a smile. Fortunately, Jessica did not turn her face away.

After looking at Xiao Yuan for a long time and saying a word, he continued to focus on the computer in front of him, leaving Xiao Yuan with a fiery red afro.

Xiao Yuan breathed a sigh of relief, found a chair from the side, called Xia Jiuying to come to him, and then focused on the material in his hand. In this material, a specific memory area was defined, and the final outcome of the memory competition was

The goal is to write a memory reading and writing program to occupy this memory area.

Defining the memory area is the most important rule in the material. In addition, the material also mentions some other precautions. For example, the programs of both sides of the competition can only be run with the permissions of ordinary users, and the method of judging victory, etc.

wait.

"Han Xiaoyu, let me ask you a question." Xiao Yuan quickly read through the materials and then said to Han Xiaoyu who was waiting aside.

"What's the question?" Han Xiaoyu was currently staring at Tang Xinxin, who was sitting not far from him. When he heard that Xiao Yuan had a question to ask, he turned around and asked.

"It is mentioned in the rules that the program we designed can only be run with the permissions of ordinary users. So, after running, if we can seize the super user permissions of the system through some means, is it considered a violation?" Xiao Yuan asked.

"I suggest you focus on the algorithm and don't think about seizing the super user. However, if you can seize the super user, it is not a violation." Before Han Xiaoyu could answer, Jessica answered Xiao Yuan for him.

question, but this time she didn't raise her head again.

Xiao Yuan was stunned for a moment. The question he asked Han Xiaoyu just now was in Chinese. He didn't expect Jessica to understand Chinese.

"Jessica is right. If you can seize the super user rights, I will automatically admit defeat." Han Xiaoyu said.

"Understood." Xiao Yuan said to Han Xiaoyu after understanding the situation. After that, he expressed his gratitude to Jessica, but this time he did not get a response from Jessica.

Xiao Yuan didn't take it seriously. Then he checked the programming environment and some software packages he wanted to use, and found that these software packages were available, and these software packages were all standard bsd software packages.

This result increased his confidence a little, so he signaled to Han Xiaoyu that he could start.

"Han Xiaoyu took out a digital watch from his desk, called up the counter, set the time for one hour, and said to Xiao Yuan, "Now the timer starts. The one-hour programming time is not long, so hurry up.

"After that, he opened the vi editor on the computer, called up a ready-made program, and stared at it.

"Han Xiaoyu, you have already written the program, but Xiao Yuan has to write it from scratch. Isn't it a bit unfair?" Wang Ping raised his own objection.

"Xiao Yuan, what do you think? If you think it's unfair, you don't have to compare." Han Xiaoyu ignored Wang Ping and asked Xiao Yuan for his opinion.

"It's okay, I don't mind." Xiao Yuan said with a smile. After that, he said to Wang Ping, "Wang Ping, don't be impatient. Let's go through a game first."

Wang Ping saw that Xiao Yuan didn't care and stopped talking, but he still looked worried.

Xiao Yuan focused his attention on his computer. Like Han Xiaoyu, he opened the vi editor on the computer and wrote the program directly in it.

Although Xiao Yuan has never written this kind of memory hegemony program, when a person's level in a certain field reaches a certain level, many problems are actually the same. This is the saying that everything remains the same.

In Xiao Yuan's mind, he conjured up a picture. Two armies were facing each other. There was a high ground between the two armies. According to a certain agreement, they would attack this high ground at a specific moment. Which side would occupy the high ground?

Which side will ultimately win after reaching this high ground?

"It is necessary to establish a headquarters to command and dispatch this war." Xiao Yuan made the decision first, and started typing on the computer with both hands. The high-speed input made the sound of keystrokes become one, as if dense.

The sound of raindrops quickly attracted everyone's attention.

Wang Ping and several other international students gathered behind Xiao Yuanshi. Seeing the programs that appeared on the computer in front of Xiao Yuan, their eyes involuntarily showed surprise. The students who came with Wang Ping were either

Computer majors, or related to computer majors, although they are not this change

Although he is a member of the State Science Laboratory, his ability to study at Berkeley is beyond the reach of ordinary computer science students. Therefore, although Xiao Yuan’s program only uses include statements for the C language header files that need to be used,

Even writing it down made them feel very shocked.

"This guy is so familiar with the bsd software library?!"

It is estimated that this is the same idea as Wang Pingping and his students at the moment. It is no wonder that they have this idea. You must know that there are hundreds of header files in the bsd software package, each of which defines some specific functions. Write a program,

Which header files need to be used and in what order should these header files be included at the beginning of the program section are all particular.

When ordinary people write programs, they usually need to repeatedly consult the BSD header file documentation or source code to finally determine which header files to use and in what order to include them into their own C language program. Wang Ping and others

People generally do this when writing programs.

Xiao Yuan can now correctly write the header files that need to be included without consulting any information. Moreover, when writing these header files, he also uses such an abnormal speed. This can only explain one problem, that is, Xiao Yuan has no interest in bsd.

He knew the software packages like the back of his hand, comparable to some old programmers who had been immersed in the BSD system for many years, but he was just a freshman who was only nineteen years old. The contrast created by this made Wang Pingping and others shocked.

Not only Wang Ping and the others, Han Xiaoyu also turned to look at Xiao Yuan for a long time, with a strange light flashing in his eyes. It seemed that he was very curious about the program written by Xiao Yuan, but it was only limited to the rules. He was not like Wang Ping and the others.

I went over to watch, so after looking at Xiao Yuan a few times, I focused on my own program.

The other two men in the laboratory were also attracted by Xiao Yuan. One of the men left his seat and came behind Xiao Yuan. He and Wang Ping gathered around to watch. After watching for a while, his original curious expression changed.

Become solemn.

Xia Jiuying sat next to Xiao Yuan, leaning on the table with her elbows and holding her chin in her hands, staring at Xiao Yuan's side face. Her thoughts were a little different from others. People often say that men who focus on doing things are the most attractive. There is no doubt that,

This sentence came true for Xia Jiuying at this moment.

At this moment, she completely turned a blind eye to the onlookers, and focused all her attention on Xiao Yuan. There was a glint of obsession in her eyes, and her heart was filled with sweetness and pride, and she became more and more determined to have Xiao Yuan in her hands in this life.

Here, never let go again.

Tang Xinxin was sitting on the other side of Han Xiaoyu, holding a small mirror to admire herself. When Xiao Yuan became the focus of almost everyone in the laboratory, she also turned to look at Xiao Yuan, sneered, withdrew her gaze, and said to Han Xiaoyu

: "Xiaoyu, you must defeat Xiao Yuan, don't let me down."

"Don't worry, Xiao Yuan has no chance of winning." Han Xiaoyu looked very excited when he saw Tang Xinxin taking the initiative to talk to him, so he shook his fist and said confidently.
