Yuxing smiled noncommittally, and replied via voice transmission: How did you deal with it?

I haven't touched those devices for the time being, I want to ask the boss for your opinion.

Let them play!Yuxing said lightly.

Yes!

After communicating with She Xiaojin, Yuxing declined the proposal of the members of the group to eat together, and returned to the dormitory alone, intending to seize the time to practice.

When I arrived at the dormitory, it was only 25:25. Yu Xing sat for another three hours, and it was only at 300:[-] that I finally finished my work.During this period, Yu Xing did not enter the land of enshrouding to practice, but only meditated on the floor, so his physical strength has reached more than [-] points, while his spiritual value has dropped to about [-].

Opening his eyes, Yu Xing sighed slightly: "It's not enough..."

The cia paparazzi who were monitoring were confused by Yu Xing's words and were confused.

"Fake, the target has said this for three hours since he came back, did he find something?" Seaside said.

"Probably not, didn't you see that the target was so quiet as soon as he came back?" Jeremy shook his head and said, "Since he came back, there were only some footsteps, not even the sound of checking things, how could we find our device? "

This made sense, and several other paparazzi nodded in agreement.

"Captain, why don't we ask those people from the FBI to find an excuse to go up and check!" Folger suggested.

Garden glared at him and said, "Do you think your family runs the FBI? Massimo's gang is not so easy to order. Besides, they are now involved in the incident of the Ross (Child) family. Wouldn’t it be stupid for us to order them privately at this time?”

Foljie had only entered the cia not long ago, and he didn't know how serious it was, so he curled his lips and said, "Is it so serious?"

Garden didn't even bother to pay attention to him, took the headset and continued listening.The other two also immersed themselves in their work, avoiding Folger like a plague god.

But within a few minutes, the four of them realized something was wrong, because there was no sound from the monitor.Quiet enough to infiltrate people to death.

"Damn, that's not right!" Gardenen cursed, and ordered: "Sesider, use the locator to check the location of our equipment immediately!"

Seaside began to frantically tap on the keyboard in front of him.A few seconds later, he said: "Captain, the equipment is still in its original position."

Garden frowned.But Folger looked at his watch and said, "Captain, the afternoon game is about to start at this point. It's not surprising that the target left the room to compete."

"What about the sound of his leaving footsteps?" Gardenen asked back, but Folger was speechless.

Garden was not wrong to be suspicious.Yu Xing teleported to the roof of the competition venue as early as the moment he finished work and stood up, and then hurried to the venue just before the official start of the competition in the afternoon.

Since the total number of participants from the two prestigious schools in the afternoon competition was less than 200, more than [-] people from Massachusetts sat together, but even so.The entire large computer room is not yet filled to two-thirds, and the distance between players is also widened.

Coincidentally, Yuxing's front and back are Ni Ni and Xiao Ne, and the left and right are Tracy and Lilian.

Apparently, the incident of lengthening Lincoln's explosion left a shadow in Lilian's heart. She saw Yu Xing as if a party member saw an organization. : "My name is this, what's your name?"

Yuxing glanced at it.After discovering that the full name of this black-haired beauty was Loel Lillian, she said, "If that's the case, call me king!"

Lilian made a rare joke and said, "King?"

Yu Xing spread his hands and said, "I can't help you if you want to translate it literally!" "

"I haven't looked for it, what's the matter?" Yu Xing wondered, "Did they look for you?"

"Yes!" Lilian looked a little depressed. "I also found Tracy."

Tracy over there looks heavier than Lilian, seeing Yu Xing looking over.She just smiled at him reluctantly, apparently the lengthening of the Lincoln bombing incident completely sank her into it.But it also proves that, despite Tracy's carefree nature, her personality seems to be stronger than Lilian's, but when things really happen, she becomes cowardly.Fortunately, she is a girl, understandable.

"Shouldn't it? This kind of case should be taken over by the FBI!" Yu Xing frowned, and then asked casually, "Did the people from the Police Bureau make things difficult for you?"

Lilian shook her head and didn't say anything. It was obvious that she had been wronged more or less.

At this time, the old professor on the spot greeted: "Classmates, don't whisper, the competition is about to start."

Yu Xing hurriedly asked Lilian to go back to her seat, while she was also sitting upright.

The fifth round of the competition started soon, and it was also a programming problem. The problem seemed much simpler than the third and fourth rounds, but after a careful study, Yu Xing found something strange in it.

It is said that there is a computer that randomly refreshes the letters on the full screen from time to time, and the spacing between the letters is uncertain. The specific requirement is to write a program to arrange the same letters on the screen together. The bcd goes down in turn to form a pattern that can move on the screen, and you're done.

At first glance, this question seems very simple, but if you think about it carefully, there are big problems here.First of all, the letters are refreshed on the screen from time to time. This is just a text description. It has to be realized by a program, and then it is arranged into an active pattern, refreshed and arranged again, and finally forms a cycle.

But as we all know, infinite loops are undesirable in programs, or infinite loops are harmful.To put it bluntly, isn't the original computer virus just taking up computer resources in an infinite loop, replicating itself and infecting different computer files?

Yuxing Yuepin felt that this programming question was a bit like eating a snake.The so-called Snake here is not a Snake game, but a virus called Snake. Its characteristic is very simple, that is, it swallows the infected computer files one by one in order of naming, and then infects them. Another computer.Of course, this is just the most basic. There are many variants of the snake-eating virus. As far as Yu Xing knows, two of them are the most powerful.

The first one is that after the snake virus swallows the file, it is directly and secretly transmitted to a remote ip. In this way, when the owner thinks that his computer has been completely destroyed by the virus, the virus spreader already has the file. All files and data on the main computer of the bit machine.

The second is even more frightening, it can no longer be regarded as a virus, because its destructiveness is minimal, it just bites all the files according to the law of greedy snakes, the files are still there and the same as before, just greedy However, the snake sends each file to the remote IP as a copy during the biting process. The whole process is no different from hackers stealing computer data without knowing it, and it is more intelligent, a kind of intelligence that only belongs to the program change.

Fortunately, this kind of intelligence is only the most elementary intelligence, and the traces of man-made orders are still very heavy, so Yuxing didn't take this mutant virus seriously after he had the intelligence of Yinsha.But now, in the game, he saw the shadow of that virus again.

Fortunately, it's just a prototype, otherwise Yu Xing would have called conspiracy.However, since he knew about the snake-eating virus, Yu Xing was able to handle this problem very well. After thinking about it for a while, he wrote a well-regulated program to solve this competition problem.

Since it is not a team battle as imagined, but a programming problem that has been done in previous rounds, Yuxing is naturally helpless to the six members of the same team. After all, their programming habits and programming speed have been recorded in the database. The members of the committee already knew it well, and it was unrealistic for Yuxing to try to pull them over again.

After running the program he wrote, seeing that the functions of the question had been realized, Yu Xing clicked submit and left the examination room.Since he couldn't help his teammates, it wouldn't be interesting for him to sit here any longer, he might as well go back to practice.

As soon as he returned to the downstairs of the dormitory, Yu Xing ran into the little devil Noda again.This time, the dog is not so arrogant anymore, but he still looks at Yu Xing with hatred.

Yu Xing sneered and said, "Little devil, I heard you were eliminated?"

Noda's expression turned ferocious in an instant, wishing he could be stripped alive.

Yu Xing was not afraid at all, and jokingly said: "Why stare? If staring is useful, why do you want to compete?" After speaking, he laughed and went upstairs.

At the same time, in the capital city far across the ocean, Zhong Nan Hai.

In Diao Heping's office, the special line of the Military Commission rang frantically.

Diao Heping, who was reviewing the documents, didn't dare to delay, grabbed the microphone and said, "Hi, I'm Diao Heping!"

"Chief, I am a young man, I have great news!"

Hearing the word 'good news', Diao Heping's serious face softened a little, and he said with a smile: "Let me guess, the sea wolf provided by Haoyu has passed the test and can be launched in advance?"

"Although your guess is not right, it is not far away!" Zhang Youxia flattered, and continued: "Our first batch of 871 sea wolves that have passed the backdoor detection of software and hardware are ready to launch, and all the technical units are in place. The most important thing is that after the internal test of Institute [-], the comprehensiveness of this batch of sea wolves can be two to three floors higher than the one we bought from the black market."

"Oh!?" Diao Heping was taken aback inwardly, but said, "Just such a little good news?"

"Of course it's more than that!" Zhang Youxia said, "I heard that those old professors from the Institute of Physics, Chinese Academy of Sciences have completely confirmed the feasibility of the formula provided by Haoyu."

"Is it feasible for military use or civilian use?" Diao Heping asked.

"It seems to work on both sides."

"Haha, you, the Military Commission, don't even know what's going on. It seems that the Chinese Academy of Sciences is doing a good job of keeping secrets!" Diao Heping said with a smile, "It seems that I have to call a meeting with experts, so I might as well ask!"

"Chief, you have to call me then, I also want to know about the situation!" Zhang Youxia hurriedly said.

"Don't worry, your seat is indispensable."
