Europe, Zurich, Switzerland, 2 p.m.

    ACM International Undergraduate Program Design Competition officially opened in Zurich''s central stadium. The competition is sponsored by world-renowned computer research institutions and sponsored by world-renowned computer brands.

    It is the most influential competition in the field of computer for college students.

    Numerous talented researchers in computer field have participated in ACM International Undergraduate Program Design Competition.

    Even the vice president of a world-famous computer brand that sponsored ACM International Undergraduate Program Design Competition once participated in ACM competition.

    In the 1990s and after the 21st century, ACM International undergraduate program design competition has been sponsored, so the scale of the competition is expanding, and the number of participating universities has increased from dozens at the beginning to hundreds or even thousands.

    Of course, these thousands of colleges and universities will be screened in their competition area after they sign up for ACM International Undergraduate programming competition.

    Finally, the colleges and universities that can go to the stage of the global finals are also the top ones.

    Ding Yue took a brief look at the list of this year''s finals -

    Imperial College

    University of Chicago

    California Institute of technology

    University of California, Berkeley

    Nanyang Technological University

    Haicheng Jiaotong University

    Moscow State University

    Federal Polytechnic University of Zurich

    St. Petersburg State University

    Melbourne University Learning

    which university is not a world-famous university?

    And the computer professional strength of these universities are very strong, whether from the teaching ability, or from the scientific research ability.

    Of course.

    Ding Yue''s Computer Department of Wucheng University of Arts and science can participate in the finals of ACM competition with this world-famous university.

    This shows that Wucheng University of Arts and Sciences has a chance to become a world-class computer major.

    it depends on Xu Bin, Chen Jun and Ouyang Chen. Can the three of them be awesome?

    If you become famous in the ACM competition, the computer major of Wucheng University of Arts and sciences will become a big choice for many domestic students who love the computer field. I''m afraid that the enrollment of computer major will soar in September next year.

    However, Ding Yue still does not know whether Xu Bin and his family can fight their way out of this smokeless battle.

    After all, Ding Yue has so far added buffs to Xu Bin and Chen Jun in their professional fields.

    Even if it''s temporary cramming, it''s useless.

    So Ding Yue quietly waited for the performances of Xu Bin, Chen Jun and Ou Yangchen.

    Ding Yue also has a specific look at the competition rules of ACM International Undergraduate programming competition.

    Each team in each university will use one computer, and need to use CC + +, Java, Python and other languages to write a program to solve 7 to 13 problems within 5 hours of the total schedule time.

    After the program of each university team is completed, it will be submitted to the referee for running. The running results will be judged to be correct or wrong, and the team will be informed in time. Interestingly, after each team completes a question correctly, the organizer will raise a balloon representing the color of the question on its position. The first team that solves each question will also get an additional "first-problemsol" "Ved" balloon.

    The final winner is the team with the most correct answers and the least total time.

    During the competition, the time of each question will be from the beginning of the competition to the end when the answer is judged to be correct. In the meantime, if the result of each submission is judged to be wrong, it will be fined 20 minutes.

    In the five hours of competition, there are generally seven or more questions, which are completed by three competitors of the same team using the same computer. When one question is solved, it will be submitted to the judges, who will judge whether it is correct.

    If the submitted program does not run correctly, the program will be returned to the participating team, and the participating team can modify it and submit the problem again.

    Generally, there are seven kinds of program judgment results -

    1, accepted - that is, passed! (AC)

    2. Wrong answer.

    the program was. (RE)

    4. Timelimitexceeded. The program didn''t give an answer within the specified time. (TLE)

    5. Presentation error -- format error. The program did not output the answer in the specified format. (PE)

    6. Memorylimitexceeded -- super memory. The program didn''t give an answer in the prescribed space. (MLE)7. Compileerror -- a compilation error. The program does not compile well. (CE)

    generally speaking, ACM International Undergraduate Program Design Competition is to let the team members of the participating teams of colleges and universities work together to solve the problems of the competition committee through computer programs in the fastest time.

    For this international competition in the field of computer for college students, there are also live broadcast in China, and it is also live broadcast by CCTV.

    It''s just a live broadcast on the science and education channel.

    As we all know, national television generally only has news channel, first channel, variety channel and other channels, and the traffic is relatively large.

    The audience of science and education channel is limited.

    It''s two o''clock in the afternoon in Switzerland, and it''s about nine o''clock in the evening in Xiaguo.

    The science and education channel of the state television station has carried out satellite relay on ACM. Although the picture synchronization is slower, at least the domestic audience can see this competition.

    "Xiao Zhang, have you found that this year''s ACM competition seems to have tens of thousands more spectators than before."

    CCTV science and education channel is in charge of the ACM competition broadcast staff after looking at the background data, can''t help but to colleagues Xiao Zhang said.

    "Is it?"

    Xiao Zhang was quite surprised.

    In previous ACM competitions, the number of spectators was basically fixed, with a maximum of 5000 people floating up and down.

    But just now, my colleague said that tens of thousands of audiences have suddenly increased this year?

    So Xiao Zhang went to watch the watching data of ACM competition live broadcast on science and education channel of CCTV.

    It''s true that there are more than 20000 people, nearly 30000 more.

    You know, if you want to watch the live broadcast of ACM competition, you can only watch it on the science and education channel of national TV''s official website. After all, only the science and education channel of national TV will broadcast the ACM competition.

    So it''s very simple for CCTV to count audience data.

    But they don''t know where the extra 20000 or 30000 people came from?

    We can''t have a fixed number of audiences in previous years, but this year we suddenly have more audiences, right?

    At this time, Wucheng University of Arts and science was thousands of miles away.

    Many of the students are Xiao Zhang of the national TV station. They don''t know where the audience is.

    The students of Wucheng University of Arts and sciences know that around nine o''clock this evening is the opening time of ACM International Undergraduate programming competition.

    Although President Ding and director Xu are far away in Europe and Switzerland, the students of Wucheng University of Arts and Sciences spontaneously organized to watch the live broadcast of the event.

    This ACM competition will be broadcast live only by science and education channel of CCTV, so everyone flocked to science and education channel of CCTV''s official website tonight.

    Although ACM International undergraduate program design competition has little attention outside the university computer professional circle.

    But for every student in Wucheng University of Arts and science, this is a competition that they should pay attention to, not just the computer students.

    Because in this competition, if my alma mater Wucheng University of Arts and sciences can get a good result, the social status of Wucheng University of Arts and sciences will obviously be improved.

    Most importantly, every student in Wucheng University of Arts and Sciences has a very warm sense of honor and disgrace, and the honor of the university is also very important to the students.

    Who makes this the second home for the students?

    In Zurich central stadium, teams from 34 universities all over the world have been in place for the finals.

    Ding Yue, Huang Youjie and Secretary Wen Ruohan watched the competition in the rest area of Xia Guo''s participating universities.

    On the field, there are 34 colleges and universities, each of which has three teams.

    Because the rule of the competition is that there are at most three members, then every university will definitely choose three players. After all, if there are many people, the procedure will be more efficient.

    "Chen Jun, you are responsible for the analysis of each topic. Ouyang Chen, you are responsible for assisting Chen Jun to provide all the help he needs, and then I am responsible for writing the program!"

    Xu Bin has carried on an accurate division of labor to this competition.

    Because ACM competition is more efficient than, who can solve the problem faster, who can be closer to the championship.

    Each team will only provide one computer for answering questions.

    In this case, Xu Bin will be assigned to control the computer to write a program to answer questions, while Chen Jun and Ou Yangchen can concentrate their energy on solving each question.

    In 5 hours, at least 7 questions or more should be answered, and the team with the least time can win.

    So the team cooperation and efficient division of labor among three people are very important for this competition.

    "Good director Xu, I will use the most concise way to analyze the questions, so that you can better answer the questions."Chen Jun nodded and answered earnestly.

    Ouyang Chen also nodded, although his work is the most "simple", but he will not relax.

    Because Ouyang Chen is very clear that he is an indispensable part of the team, and he must do his best to assist Chen Jun in the analysis of the topic, so that the team can achieve the best results.

    In the whole team, it is obvious that Xu Bin''s work is the most difficult, because after Chen Jun and Ou Yangchen''s analysis, Xu Bin needs to write a program to answer the questions.

    Of course, in the process of answering questions, if they encounter any difficulties, Chen Jun and Ou Yangchen will also play an important role in Xu Bin''s think tank.

    In fact, most of the teams in participating universities are basically Xu Bin''s model.

    The details may be different, but the division of labor must be clear.

    Xu Bin will not despise his rivals, because they are all from the world''s top computer universities.

    It''s no exaggeration to say that 102 contestants from 34 teams on the spot are all computer talents!

    It''s true!

    [live broadcast room of science and education channel of national TV station] -

    "I saw our university team in Xia, Haicheng Jiaotong University."

    "Haicheng Jiaotong University once won the championship in ACM competition, and more than once, he is the biggest winner in our country."

    "This year, there are still Moscow State University and St. Petersburg State University, which seem to be very strong in recent years."

    "It''s true that Moscow State University and St. Petersburg State University have basically won the championship in the past few years, but if you think about it, the teams they used to compete in have graduated? Can the new team still take over the banner of the champion and defend the title? "

    "Hahaha, I see our Northwest University of science and technology!"

    "To tell you the truth, this year''s Wucheng University of Arts and Sciences is really surprising. It can actually get a place to participate in the competition."

    "The students from Wucheng University of Arts and Sciences come to report for duty. Let''s go

    "I heard that Xu Bin of Wucheng University of Arts and science is very powerful. He has been worshipped by many great gods in the domestic computer circle."

    "Really? Is it so powerful? "

    "Those who have been in the computer circle should know that Xu Bin has an ID called" abin ", which is called by the computer gods - heaven does not give birth to me, abin, and the computer will last forever!"

    "So much?"

    "I''m ignorant."

    "As far as I know, this abin family seems to be able to write a super powerful operating system."

    "Like apple? Death of plague? An operating system like Android? It''s true. It''s so exaggerated. "

    "It''s just a rumor. No one has seen the operating system made by abin himself. Who can''t boast?"

    "So, the team of Wucheng University of Arts and Sciences really has something?"

    "Let''s wait and see. Did you stay up late to watch the game tonight?"

    "Tomorrow, Saturday, I''m sure I''ll finish watching the game. It''s only about two o''clock after watching it, and the night life will officially start."

    "666, can you all stay up so late?"

    At this time, Xu Bin obviously did not know that he was being discussed by domestic netizens watching the game.

    His energy is all in the game.

    The ACM competition committee soon determined that 34 university teams were ready.

    Then we start to give the first question.

    That is [Topic A].

    ACM competition questions will be given one by one in the form of ABCDEFG, and then all teams will begin to answer the questions.

    And the difficulty of the topic, obviously also from a, will be more and more difficult!

    When the first question was given out, all the team members of the 34 university teams immediately entered the state.

    It is worthy of being one of the top computer majors in the world.

    "Chen Jun, start to analyze the topic."

    "All right!"

    Chen Jun began to analyze [Topic A], which is also the most convenient way for him to communicate with director Xu.

    The purpose is to let Xu Bin write the problem-solving program according to the analysis of the topic more efficiently.

    In other words, Xu Bin, they can start to answer questions while analyzing questions, which is not comparable to the efficiency of the general team!
