For two days on the weekend, Mu Xuan and the three of them had a very comfortable time, that kind of leisurely feeling, the three of them were happy to indulge in it, and the most important source of this feeling was that the three of them could be together.

Life at this moment, it seems to be very beautiful, really beautiful!

The two days disappeared quickly, and tomorrow was a new week, and Mu Xuan planned to ask specifically about skipping a grade when he went to school tomorrow.

Although Mu Xuan and Zhang Yue's sister and brother are together, Mu Xuan can clearly feel the gap between the two, and this gap does not know what kind of changes will occur, so Mu Xuan must take the initiative to shorten the gap between the two, and the first step to shorten the gap, Mu Xuan intends to skip a grade and shorten the gap in time.

The next day, there was no longer the warm feeling of yesterday, and the sky was filled with a faint mist, with a hint of coolness.

There is never a shortage of people walking quickly on the campus of Peking University, as for the reason, there is no point in delving into it, Mu Xuan and Zhang Yue separated after they came to the school, and the two had already said that they would go to the Academic Affairs Office together after the second class to consult Mu Xuan about skipping a grade.

Time was in a hurry, the first class ended quickly, and after Mu Xuan called Zhang Yue, he disappeared into the crowd.

"Mu Xuan" When Mu Xuan was waiting in the position agreed by the two, Zhang Yue's voice came from behind.

"Sister, Sister Yunyun." Mu Xuan turned around, but found Zhang Yue and Bai Yunyun.

"Brother Mu Xuan, I heard that you want to skip a grade? Aren't you in the same class as me from now on? Bai Yunyun blinked her cold eyes and teased Mu Xuan.

"Sister Yunyun, I don't know if I can be successful enough?" There was a wry smile on the corner of Mu Xuan's mouth. Anyway, he hadn't heard of that college student being able to skip a grade before.

"Then let's go to the Academic Affairs Office and ask. Although the number of college students skipping grades is very small. But logically speaking, it should be possible to skip a grade. Zhang Yue interjected.

"Well, let's go." Mu Xuan said, and then the three of them walked towards the Academic Affairs Office.

Knock knock knock

When Zhang Yue came to the door of the Academic Affairs Office, he gently knocked on the door.

"Please come in." After Zhang Yue knocked on the door, a female voice came from inside.

"Director Xie, we want to ask some questions about whether freshmen can skip grades, who do you think is more suitable?" Zhang Yue came to the position of the director closest to the door, and there was his nameplate in front of the director's desk. Zhang Yue is called according to the above information.

"You go to consult Director Zhao over there for this question, he is the person in charge of this." Director Xie smiled kindly, and pointed out the location of Zhang Yue and the others with his hand.

"Thank you, Director Xie!" Zhang Yue politely thanked him.

"You're welcome!" Director Xie smiled kindly again.

Mu Xuan and the three of them came to Director Zhao's position, and Zhang Yue said: "Director Zhao, I want to consult about skipping grades, do you have time now?" ”

"Yes, but which of you wants to skip a grade?" Director Zhao raised the thick eyes on the bridge of his nose and asked.

"Director Zhao, it's me. I want to skip a grade to my sophomore year, what do you think are the requirements? Mu Xuan replied.

"What are you majoring in?" Director Zhao slid his gaze from Zhang Yue's body to Mu Xuan's body. Then asked again.

"I'm in the software engineering department. Major in Software Programming. Mu Xuan responded.

"Oh, why do you need to skip a grade?" Director Zhao asked.

"I want to finish my studies as soon as possible." Mu Xuan seemed to have thought that the other party would ask this question, and said.

"There are very few records of students who skip grades in software engineering in the past, and skipping a grade is a very complicated thing, after skipping a grade, the homework of the freshman year still exists, but you don't have to go to class, just go directly to the exam at the end of the semester to take the corresponding subjects, and then you only use the sophomore course, and this premise is that you have to prove to the school that you have the strength to skip the grade." Director Zhao explained.

"How should that be proven?" Mu Xuan showed a hint of joy, it seems that there is still hope for skipping grades.

"At the end of the sophomore year, the ACM Programming Competition of the Alliance of Asian Universities will be held, and we at Peking University will also participate, so if you participate in the ACM Programming Competition and get the top 30 in China, you can hand me the certificate at that time." Director Zhao explained again.

"Is that so? Do you need anything else? Mu Xuan didn't know what it was like to win the top 30 in the Chinese region above the ACM Programming Competition, but he had heard that the ACM Programming League was held once a year, and it seemed to be very valuable.

"No, this one will do." Director Zhao replied patiently.

"Then thank you, Director Zhao." Mu Xuan thanked him.

The three of them closed the door of the room in the Academic Affairs Office, and Zhang Yue said, "Yunyun, haven't you participated in the ACM Programming Competition before?" ”

When Mu Xuan heard this, he also turned his head to look at Bai Yunyun, but found that Bai Yunyun's cold face was a little unnatural, and Bai Yunyun didn't have the slightest intention of answering.

"Yunyun, I'm sorry." Zhang Yue looked at Bai Yunyun like this, and then reacted, and immediately apologized, because Zhang Yue knew that he seemed to have touched Bai Yunyun's sadness.

"Jaw, Yueyue, I'm fine, I'm just a little emotional." Bai Yunyun heard Zhang Yue's apology and found that Zhang Yue seemed to have misunderstood herself.

"I didn't want to participate in the ACM Programming Contest this year, but since Brother Mu Xuan is going to skip a grade, then I'll help you!" Bai Yunyun slowly recovered from her previous state of distraction and said.

"Why?" Mu Xuan was a little puzzled, why he skipped a grade, Bai Yunyun had to participate in the ACM programming competition.

"Because the ACM Programming Contest is a team registration, and the team must be from the same school." Zhang Yue explained.

"Teaming up?" Mu Xuan muttered, he really didn't know about this, and he had paid attention to it before, but he didn't care about how he participated.

The ACM Programming Competition is the highest brain competition at the university level, and has always been dubbed the "Olympiad of Programming". The competition has a history of more than 40 years since its inception in 1970, making it the oldest in the world. The largest programming competition.

The format of the competition is to select the participating groups at the regional level. with the specified time. The venue participates in the finals at the general domain level, where a team of 3 members applies a computer to solve 6 and 8 life timing problems, and the general domain level is real programming.

The history of the competition began in 1970, when the first competition was held at the University of Texas in the United States, and the organizer at that time was Thealphachapteroftheupe computerscience HonorSociety.

In 1977, the first finals were held during the ACM Computer Science Conference, which has evolved into the current annual multi-national international competition. It has been held 43 times so far.

The first few editions of the competition were mainly from the United States and Canada, and gradually developed into a worldwide competition, especially since 1997, when IBM began sponsoring the competition, the size of the competition has grown rapidly, in 1997, a total of 860 teams from 560 universities participated in the competition, and in 2004, this number has rapidly increased to 2809 teams from 840 universities, and is increasing at a rate of 10-20% per year.

In the early days of the tournament, most of the championships were won by universities in the United States and Canada. Since the late 1990s, universities in Russia and a number of other Eastern European countries have won several championships. The Shanghai Jiao Tong University team from Chinese mainland won three championships in the 26th World Finals in Hawaii in 2002, the 29th World Finals held in Shanghai in 2005 and the 34th World Finals held in Daharbing in 2010.

This is also the best result of an Asian university in this competition so far, and the competition pattern of the competition has evolved from the original North American universities to the current Asia-Europe confrontation.

"Well, there are three people in each team, now there are you, me, I'll introduce you to another person in a few days." Bai Yunyun said.

"Then thank you, Sister Yunyun." Mu Xuan said.

"You call me sister, and you're so polite." Bai Yunyun blinked and said,

"By the way, Sister Yunyun, is it difficult to enter the top 30 in China?" Mu Xuan recalled Director Zhao's explanation just now and asked.

"It's very simple, you don't have to worry at all, the school won't give you a difficult height, and besides, every sophomore may not be able to enter the top 30 in China after participating, so we still have a chance." Bai Yunyun said.

"Oh, so how many teams are there in each ACM class?" Mu Xuan asked carefully.

"It's about five thousand." Zhang Yue thought for a while.

"More than 5,000, so much?" Mu Xuan was surprised.

"You don't have to worry about this, except for more than 500 soy sauce, there are only more than 4,500 teams, we are fighting as a team, I believe in your Sister Yunyun's ability." Bai Yunyun said.

"Okay!" In fact, Mu Xuan was not worried about anything, but sighed that the number of participants was indeed a bit large.

If you want to enter the competition among more than 5,000 teams, I'm afraid that you will have to be full of corpses all over the way.

The AVM Programming Contest is held on December 1st of each year, and the time is less than a month, and the deadline is December 7th, during which there are seven days of international competitions from national and regional competitions.

Each country in Asia can only send the top three to the international competition, and the top three, will also get excellent treatment, and there are many large international companies to hunt for talents, so this is the reason why many software students choose to participate in the ACM programming competition.

"But you have to prepare well in the meantime." Bai Yunyun asked.

"Don't worry, Sister Yunyun." Mu Xuan said.

"Okay, I'll go to class first." Bai Yunyun said.

"Bye-bye, Sister Yunyun." Mu Xuan said goodbye.

"Bye-bye, rhyme." Zhang Yue also said goodbye to Bai Yunyun.

"Sister, what happened to Sister Yunyun just now?" Mu Xuan looked at Bai Yunyun's distant back and asked.

"Kid, don't ask what you shouldn't." Zhang Yuejiao said angrily, it wasn't that he didn't want to tell Mu Xuan, but he was afraid that Mu Xuan would inadvertently evoke Bai Yunyun's sad past.

"Oh." In fact, there are also some faint speculations in Mu Xuan's heart, could it be that Sister Yunyun hasn't let go yet?

"I'll go to class first, and I'll wait at my brother's side at noon." Zhang Yue waved goodbye to Mu Xuan.

"Got it." Mu Xuan said.

"A month?" Mu Xuan muttered, it seems that this month, he must also do some work. (To be continued......)
