(New book period, ask for flowers, ask for collection!) The finals of the mathematical modeling competition officially started in the morning of the next day, and after the elimination of the preliminary round, only 20 people were left to enter the finals, so the two test venues in the preliminary round became one examination room.

There is no change in the form of the written test in the morning and the preliminary round, but the difficulty has gone up to a new level, even Xiao Yuan did not finish it until the end of three hours, and after handing in the papers and coming out of the examination room, he met the little fat man, and walked out of the examination room with him, this guy couldn't help but start pouring bitter water on Xiao Yuanda, saying that the question was difficult, and Liu Dong, who walked with them, said that the question was difficult, and he didn't say a word, but it could be seen from his expression that he was not satisfied with his test today.

Xiao Yuan comforted the little fat man for a few words, and met Tang Xinyu and the others waiting there outside the examination room with him.

"How?" Tang Xinyu asked with concern.

"It's a lot harder than the preliminary round, but it's okay, it should be fine." Xiao Yuan said.

"That's good, I saw that many people who came out before were talking about difficult questions, and a few of them cried before they finished it." Tang Xinyu listened to Xiao Yuan's words and said with a sigh of relief.

"It's really hard, I can't do it well." The little fat man said loudly from the side.

"Aren't you done?" Tang Xinyu asked.

"It's done, but I don't feel good, I always feel like I'm missing something important." The little fat man said.

"Forget it, the exams are over, it's useless to think about it, let's go eat, thin classmate, how many chicken legs are you going to eat today?" Jiang Hua gaged on the side and asked with a smile.

"I want to eat three." When the little fat man heard what he was eating, his attention was immediately diverted, and he said with drooling, but then his face became bitter and said, "But Teacher Mei doesn't let me eat so much, what should I do?" ”

After speaking, this guy's chubby round face looked at Mei Li with a pitiful look, and put the index finger of his right hand to his mouth, which made Mei Li laugh and said, "Let you eat two today." ”

"Oh yes." The little fat man jumped up with joy, and his fat body trembled.

Seeing the cute appearance of the little fat man like a living treasure, Xiao Yuan and the others all laughed, and even Liu Dong, who had a cold face, turned up the corners of his mouth, and was infected by this guy............

The afternoon computer programming exam was held in the computer room of the Department of Mathematics, and the exam lasted for four hours, from two o'clock to six o'clock.

Probably because the questions in the morning were a little difficult, Xiao Yuan When they arrived, most of the students who participated in the finals had already come, and they all looked solemn, which made the atmosphere outside the examination room a little tense, Liu Dong had not yet come, but he saw Quan Shu Buying and the two, these two guys can be valued by Maninan, and it is not simple, although the results are not as good as Xiao Yuan, Little Fat and Liu Dong, but they have also entered the finals.

Maybe it was because Tang Xinyu and Mei Li were following, these two guys just sneered and looked at Xiao Yuan and the little fat man, and then left together.

When they were about to enter the venue, Liu Dong came, and Duan Yanyue and Tang Sa came with him, and their arrival immediately attracted the fiery eyes of many boys, especially when they walked to Xiao Yuan's side, which made their group the focus of almost everyone's attention.

"Brother, you take the test well, and my sister will invite you to a big meal after the test." Tang Sa came to Xiao Yuan's side and said with a smile.

"Thank you, Sister Sa."

Xiao Yuan has spoken to Tang Sa for the second time since he separated from her on National Day, and Tang Sa tore off the layer of the habitual bewitching mask that used to be in the face of him, which made him feel that there seemed to be something insurmountable between the two, and even when he spoke, he became polite.

"This sister, can I go for a big meal?" The little fat man heard that there was a big meal to eat on the side, and hurriedly drooled and asked, his interjection diluted the embarrassing atmosphere between Xiao Yuan and Tang Sa a lot.

"Giggles, the little chubby dun is so cute, come and let my sister pinch it, and my sister will take you to a big meal." Tang Sa giggled and said, and as he spoke, he was about to reach out and pinch the fat man's face.

Xiao Yuan and the others saw that Tang Sa didn't understand the situation, and even called Wang and his party a little fat dun, and secretly said that it was not good, sure enough, the little fat man hid to the side, and forgot about the big meal, and asked with a resentful face: "This sister, am I fat?" ”

"Oh my God, it's over."

Seeing this, Xiao Yuan and Jiang Hua glanced at each other, and quietly hid far away for the sake of their own ears, so Tang Sa was tragic, pestered by the little fat man, and chattered and discussed this issue, until he began to enter the scene, he had to let Tang Sa go, but he still looked back at Tang Sa step by step, with a look of resentment.

"Sister, you have suffered." When Xiao Yuan passed by Tang Sa's side, he comforted her sympathetically.

"You guy, you know that he will be like this, why didn't you remind me in advance." Tang Sa smiled wryly, rubbed his temples that were swollen by the little fat man's chatter, and complained.

"Haha, we have been tortured, Sister Sa, you will also suffer from stepping on the side." Xiao Yuan laughed, dodged Tang Sa's hand stretched out to his ear, and walked two steps to the examination room, then heard a scream behind him, turned his head to look, but it turned out to be Tang Sa with one hand on his waist and Jiang Hua's ear in the other, and walked out, so he mourned for Jiang Hua for a second in his heart, and went to the examination room with a smile.

Entering the computer room, Xiao Yuan found his seat and sat down, there was a competition operation guide posted on the computer desk, according to the operation guide, he pressed the power switch, wanted to start the computer, but found that the computer power had not been turned on, so he had to sit there and wait for the exam to start.

There were only 20 students who participated in the finals, and they soon entered the venue, and then the teacher who organized the exam stood on the podium, first emphasized the discipline of the examination room, and waited for a few minutes.

Xiao Yuan turned on his computer, and found a document called test questions on the Windows desktop according to the operation guide, after opening it, he carefully read the questions in it, and he found that the difficulty of this question is not high, probably about the same as the difficulty of the question in the preliminary round, for students who can pass the preliminary competition, it should not be a problem, but he knows that the difficulty of this exam is to program the abstract mathematical model, and the hands-on ability test occupies a large proportion. There is a big difference between pseudocode and real programs, and this difference will become a hurdle that is difficult for some students who are not strong in hands-on ability to cross, of course, all this is not a problem for Xiao Yuan himself, he can even write pseudocode without writing pseudocode, and directly write real programs, in fact, he also does this.

The invigilator sent the straw paper to everyone's hands, the computer room quickly quieted down, the first step for all candidates to do, is to read the question, from which to abstract the required mathematical model, this process lasted about an hour, when the keyboard in the computer room crackled like dense raindrops hitting the window, the tranquility of the computer room was broken for the first time, almost all the students raised their heads, looked at the sound of a few plates, but it turned out that Xiao Yuan was the first to do it, It's just that his high-speed input speed surprised all the candidates except Liu Dong and Little Fatty, and even the invigilator couldn't help but walk behind him and stand there for a while before leaving.

Quan Shu and Bu Ying were not far away, they looked at each other, a sinister smile appeared on the corner of their mouths, Quan Shu put down the question in his hand, flipped it in the computer, crackled a few times, and then began to do his own question again.

Xiao Yuan didn't notice the shock he caused to the students in the computer room, because he had a habit of ignoring everything around him when he started to focus on something, and when he focused on his program, he didn't even notice the moment when the invigilator stood behind him, and this kind of high-speed input was completely a subconscious behavior that had been carved into his bones.

After Xiao Yuan typed for a while, another student began to program, so the crackling keyboard sound in the computer room gradually came and went, and the sound became one after another, of course, these have nothing to do with Xiao Yuan, he is now all focused on the program he wrote.

Completely forgetting the concept of time, Xiao Yuan did not raise his head from the computer screen until he finally successfully debugged the program and passed the compilation, looked around, and found that almost all the students had entered the final programming stage, and it was almost three hours by this time.

He read the question again, checked the program algorithm he wrote, and felt that there was no problem, so he wanted to submit the paper in advance, and the way to submit the paper on the computer was to use the upload tool provided by the computer to compile the program and the compilation and running results, and upload it to the designated server through the LAN of the computer room, but when he opened the upload tool, selected the program he wrote, and pressed the submit button, there was an accident.

A window pops up to indicate that the source file he uploaded is corrupted, and tells him to check it before uploading it.

Xiao Yuan was stunned for a moment, quickly checked the source code he wrote, and found that the content in the text file had become a bunch of garbled characters.

"What's going on?"
