(New book period, ask for flowers, ask for collection!) The source file was damaged for no reason, which made Xiao Yuan notice something abnormal, but for the sake of insurance, he still decided to raise his hand to report to the invigilator first.

"What's the matter?" The invigilator had been paying attention to Xiao Yuan, and he found out as soon as he raised his hand, so he came over and asked.

"My source file is broken." Xiao Yuan said.

"What source file is broken?" The teacher didn't understand what Xiao Yuan meant for a while, so he came to Xiao Yuan's computer and watched Xiao Yuan demonstrate it to him, only then did he understand what was going on.

"Oh, you're more troublesome, although there is a reason for it, but there is no source file, and there is no way to score you in the future."

The teacher frowned and said, after saying this, he felt a little irresponsible, so he added, "That's it, there is still more than an hour to go, you hurry up and re-type the program, if it's too late, I'll apply to the competition committee to see if I can extend some time for you." ”

"Okay, thank you, teacher." Xiao Yuan replied that the reason why he spent nearly two hours in the previous was that most of the time was spent on ideation, and this time it should not take long to re-enter the program without re-imagining.

"Well, the rules of the competition are very strict, and you may not be able to apply for a delay, so it is best if you can rewrite it before the end of the exam." The teacher told Xiao Yuan, turned to leave, said hello to another invigilator, and turned around and walked out of the computer room.

Xiao Yuan had no choice but to re-enter, but this time he had multiple thoughts, and instead of following the requirements of the operation guide, he established the source file with the specified file name in the specified folder, but changed the place, established a source file with a different name, and began to quickly enter the computer program that he had debugged once.

When he was busy, suddenly a window popped out, interrupting Xiao Yuan's input, and after a glance, it was Liu Dong who sent it through the LAN.

"The book of power and Bu Ying are very abnormal, and it is possible that the two of them are responsible for the corruption of your source files." This is the content of the message sent by Liu Dong.

"It's okay, I'll get the procedure done first, and then I'll deal with them when I have time." Xiao Yuan sent a message back to Liu Dong.

"Okay, you just have a plan in mind, come on." Liu Dong replied with another message.

"Thanks, busy, don't go back." Xiao Yuan sent Liu Dong a message again to express his gratitude, and then began to type at high speed again, and the crackling keyboard tapping sound became a single one.

After about ten minutes, Xiao Yuan estimated the time, he should be able to finish the program in a maximum of forty minutes, and recompile and debug it, if it goes well, half an hour is enough, and his heart is much more settled, at this time, the previous invigilator led a middle-aged man in and came to Xiao Yuan's side.

"What the hell is going on?" The man asked.

"That's the case...... Xiao Yuan had to stop, explained again, and then demonstrated the executable file that he had compiled the source file into before, showing that he had actually done it, in order to save time, he said it very succinctly, and it only took less than two minutes to explain the matter clearly.

"Re-enter the source program, is there enough time?" The man asked again.

"Almost." Xiao Yuan said that although there was definitely enough time, he was not as full as he spoke.

"Okay, you hurry up and do it, and don't rush to upload it when you're done." The man instructed Xiao Yuan, and then said to the invigilator, "You go to the competition committee to get a floppy disk in a while, and make a copy of this student's source file for later use." ”

After finishing the order, he left, and the invigilator patted Xiao Yuan on the shoulder, encouraged him, and left again.

Xiao Yuan continued to re-enter by himself, and it took about twenty minutes for the source program to be re-entered and debugged, and the time display in the lower right corner of the computer screen was only half past five.

After doing all this, he raised his hand and asked the teacher to bring a floppy disk, take a copy of the written source program, and then upload his source program and compiled executable file to the server again under the teacher's guard, and sure enough, the source file was damaged again.

"Hell yes." The teacher looked suspicious.

"Teacher, I see that there is a spare computer in the computer room, why don't you compile a copy of it on another computer and upload it, it is likely that my computer is poisoned, or something else is wrong." Xiao Yuan suggested that by now, he had basically determined that his computer was poisoned, and it was likely to be the poison of Quan Shu and Bu Yingtou, although he really wanted to find out these two guys on the spot, but at this time and occasion, he was not allowed to do so, so he could only find a way to submit his source program successfully before speaking, the reason why he said that he would have to recompile it on another computer was that he was worried that the executable file he compiled was also poisoned, and the source file was just a plain text file, which would definitely not be poisonous.

"Well, that's all there is to it."

Although the more reliable way is to copy the source files directly to the server, he does not have the management rights of the server, and at the same time, in order to reduce the trouble, the teacher thought about it and adopted Xiao Yuan's suggestion.

After changing to another computer, because the source program does not need to be re-entered, the recompilation is very fast, from boot to successful compilation, Xiao Yuan took less than seven or eight minutes to complete, and there were no more accidents on this computer, Xiao Yuan's program was successfully uploaded.

After uploading the program, Xiao Yuan breathed a sigh of relief, there were still about twenty minutes to hand in the paper at this time, and the invigilator did not let Xiao Yuan leave early, but asked him to sit on the machine behind and wait, and finally left together.

"Paralyzed, it must be the ghosts of Quan Shu and Bu Ying, you can't just let them go, otherwise it will seem that I am too easy to bully!"

Xiao Yuan sat there and scolded secretly, after Liu Dong's reminder just now, Xiao Yuan also paid attention to Quan Shu and Bu Ying a few times, when all the students were attracted by his negotiation with the teacher, these two guys didn't look at him, this kind of behavior made the two of them even more suspicious, because if it wasn't for their ghosts, they would never behave like this.

There are still twenty minutes, Xiao Yuan feels that he should do something, he can't make these two guys feel better, he needs to figure out the IP address of the Quanshu Buying computer first, this job is not too difficult, but it needs to use means other than the computer.

Xiao Yuan observed that all computers in the computer room are a LAN composed of two cascaded switches, all computers have a number, the IP address of the computer starts with 192.168.0., and the last set of numbers is exactly the computer number, so as long as they can know the computer number of the right book and Bu Ying, they can know the IP address of their computer.

The problem is that the computers of the two guys are in another row, Xiao Yuan can't see them, fortunately, Liu Dong is relatively close to them, so Xiao Yuan sent a message to Liu Dong, asking him for the IP address of Quan Shu Buying, and soon Liu Dong sent a message with two numbers in it.

After getting the IP address of Quan Shubu Ying, Xiao Yuan scanned the computer room and saw that the two guys were still staring at the computer screen at this time, and it seemed that they should not have finished it, and at this time, the two invigilators were sitting on the podium and did not look at him.

"Quan Shu, Bu Ying, today I will make you really lose and win!" Xiao Yuan said secretly, but he didn't stop in his hand, a series of network orders were sent, and it was time for his counterattack.
