Start With a Fake University

Europe, Zurich, Switzerland, at two o'clock in the afternoon.

　　 ACM International College Student Programming Competition officially kicked off at the Central Stadium in Zurich. This competition is sponsored by a world-renowned computer research institution and sponsored by a world-renowned computer brand.

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

　　Countless talented researchers in the computer field have participated in the ACM International College Student Programming Competition.

　　Even the vice president of a world-renowned computer brand that sponsored the ACM International College Student Program Design Competition, once also participated in the ACM competition.

Stepping into the 1990s and after the 21st century, the ACM International College Student Programming Contest was sponsored, so the scale of the contest has continued to expand, and the number of participating universities has increased from dozens of universities to hundreds or even more. Thousands.

　　 Of course, after these thousands of universities sign up for the ACM International College Student Programming Competition, they will conduct certain screenings in their competition area.

　　 The colleges and universities that can finally make it to the stage of the global finals are also the top batches that have come out of the big wave.

　　 Ding Yue briefly looked at the list of entries in this year's finals——

　　 Imperial College

University of Chicago

　　 California Institute of Technology

UC Berkeley

　　 Nanyang Technological University

　　 Haicheng Jiaotong University

　　 Moscow State University

　　 ETH Zurich

　　 Saint Petersburg State University

University of Melbourne

　　 Looking at it this time, which one is not a world-renowned university?

　　Moreover, the computer expertise of these colleges and universities is very strong, whether it is from teaching ability or scientific research ability.

Of course.

　　 Ding Yue’s Department of Computer Science, Wucheng University of Arts and Sciences can participate in the finals of the ACM competition with this world-renowned university.

　　This shows that Wucheng University of Arts and Sciences has the opportunity to become the world's first-class level in the field of computer science.

　　 It depends on whether Xu Bin, Chen Jun and Ouyang Chen can work hard.

　　 If you become famous in the ACM competition, the computer major of Wucheng University of Arts and Sciences will become a major choice for many domestic students who love the computer field. In September next year, the enrollment of computer majors may skyrocket.

　　 It's just that Ding Yue still doesn't know whether Xu Bin and the others can make a **** way out of this battle without gunpowder.

　　 After all, Ding Yue has added all the professional BUFFs that should be added to Xu Bin and Chen Jun.

　　 It's useless even if it's temporarily embracing the Buddha's feet.

　　 So Ding Yue quietly waited for the performance of Xu Bin, Chen Jun and Ouyang Chen in the game.

　　 Ding Yue also took a look at the competition rules of the ACM International College Student Programming Contest.

　　Each team in each university will use 1 computer, and need to use a programming program in C/on and other languages ​​to solve 7 to 13 questions within 5 hours of the total schedule.

After the procedures of the participating teams in various universities are completed, they will be submitted to the referee to run. The results of the operation will be judged as correct or incorrect and the team will be notified in time. What is interesting is that after each team has completed a question correctly, the organizer will rise in its position A balloon representing the color of the question, the first team to solve it for each question will also get an additional "FIRST-PROBLEM-SOLVED" balloon.

　　 The final winner, that is, the overall champion is the team with the most correct answers and the least amount of time.

　　During the competition, each test question will take time from the start of the contest to the time the test question solution is judged to be correct, during which a penalty of 20 minutes will be imposed for each submission of the running result and judged to be wrong.

Within 5 hours of the competition, there are generally 7 or more test questions, which are completed by three players from the same team using the same computer. When a test question is solved, it is submitted to the judges, and the judges judge whether it is correct .

　　 If the submitted program does not run correctly, the program will be returned to the team, and the team can make changes and submit the available question again.

　　 There are generally 7 types of program judgment results——

　　1-Pass! (AC)

　　2, Wrong　　Answer——that is, the answer is wrong. (WA)

　　3, Runtime　　Error——that is, program operation error, unexpected termination, etc. (RE)

　　4, Time　　Limit　　Exceeded.——that is, timeout. The program did not give an answer within the specified time. (TLE)

　　5, 　　Error——that is, the format is wrong. The program did not output the answer in the prescribed format. (PE)

　　6, Memory　　Limit　　Exceeded-namely super memory. The program did not give an answer in the prescribed space. (MLE)

　　7, Compile　　Error——Compile error. The program does not compile. (CE)

　　 In general, the ACM International College Student Programming Competition is to allow the team members of the participating teams of various universities to work together in the fastest time to solve the problems of the competition committee through computer programs.

　　 For this international college student computer field competition, there is also a live broadcast in China, and it is also broadcasted by National Television Station.

　　 is just a live broadcast on the science and education channel.

　　 As we all know, China National Television generally only has a few channels such as News Channel, Channel One, and Variety Show, which have relatively large traffic.

　　 The number of viewers on the Science and Education Channel is limited.

　　 It was two o'clock in the afternoon in Switzerland, and in Xia Guo, it was already around nine o'clock in the evening.

　　 The Science and Education Channel of the National Television Station broadcasted the ACM through satellite. Although the picture synchronization is slower, it can let the domestic audience see the game.

　　 "Xiao Zhang, have you noticed, this year's ACM competition, the number of spectators seems to be tens of thousands more than before."

　　 The staff of the Science and Education Channel of China National Television Station who was in charge of the broadcast of the ACM competition, after looking at the background data, couldn't help but tell his colleague Xiao Zhang.

"is it?"

　　 Xiao Zhang was surprised when he heard it.

　　 In each previous ACM competition, the number of spectators was basically fixed, with a maximum of 5,000 people fluctuating.

　　 But just now my colleague said that there were tens of thousands of viewers suddenly added this year?

　　 So Xiao Zhang went to check the viewing data of the viewers who were broadcasting the live broadcast of the ACM competition on the Science and Education Channel of China National Television.

　　 is indeed more than 20,000 and nearly 30,000 people.

　　 You need to know that if you want to watch the live broadcast of the ACM competition, you can only watch it on the science and education channel on the official website of China National Television. After all, only the science and education channel of China Television Station will broadcast the ACM competition.

　　 Therefore, it is very simple for China National Television to count the audience data.

　　 It’s just that Xiao Zhang and the others don’t know at all, where did the extra 20,000 or 30,000 viewers come from?

　　 You can't always have a fixed number of viewers in previous years. This year, suddenly there will be more audiences, right?

　　 At this time, Wucheng University of Arts and Sciences is thousands of miles away.

　　Many students are viewers from China TV station Xiao Zhang, they don’t know where to pop up.

　　The students of Wucheng University of Arts and Sciences know that around nine o'clock this evening is the start time of the ACM International College Student Programming Contest.

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

　　 And for this live broadcast of the ACM competition, only the Science and Education Channel of National TV Station will be broadcasted. Therefore, everyone swarmed to the Science and Education Channel of the official website of National TV Station tonight.

　　Although the ACM International College Student Program Design Competition has little attention outside the university computer professional circle.

　　 But for every student of Wucheng University of Arts and Sciences, this is an event worthy of their attention, not just computer students.

　　Because of this event, 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.

　　The most important thing is that every student at Wucheng University of Arts and Sciences has a very warm sense of honor and disgrace. The honor of the school is also very important to the students.

　　Who makes this the second home of the students?

　　 In the Zurich Central Stadium, all teams from 34 universities around the world have been in place for the finals.

　　 Ding Yue, Huang Youjie, and secretary Wen Ruohan were in the rest area of ​​Xia Guo’s participating colleges, watching the game.

　　 There are 34 colleges and universities on the field, and each college has three teams.

　　Because the rules of the tournament are three members at most, then every college will definitely choose three players. After all, if there are more people, it will be more efficient to solve the program.

　　 "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 made an accurate division of labor for this game.

　　Because the ACM competition is more efficient, whoever solves the problem faster will be able to get closer to the throne of the championship.

　　 And each team will only provide one computer for answering questions.

　　 If this is the case, Xu Bin will assign it, and he will control the computer to write the program to answer the questions, and Chen Jun and Ouyang Chen can concentrate their energy on analyzing each question.

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

　　 So the teamwork between the three people and the efficient division of labor are very important for this competition.

　　 "Good Director Xu, I will use the most concise way to parse out the questions, and strive to enable you to answer the questions better."

　　 Chen Jun nodded and replied seriously.

　　 Ouyang Chen also nodded, even though the work he did was the most "simple", he would not relax in the slightest.

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

　　 In the entire team, Xu Bin’s work is obviously the most difficult, because after Chen Jun and Ouyang Chen have resolved the questions, Xu Bin needs to write a program to answer the questions.

　　 Of course, in the process of answering questions, if you encounter any difficulties, Chen Jun and Ouyang Chen will also play important roles in Xu Bin's think tank.

　　 In fact, most of the team assignments of participating universities are basically based on Xu Bin's model.

　　 may be different in subtleties, but the division of labor must be clear.

　　 Xu Bin will not underestimate his opponents, because they are all from the world's top computer professional universities.

　　 It is not an exaggeration to say that 102 players from the 34 participating teams are all computer geniuses!

　　 This is indeed the case!

　　【National TV Science and Education Channel Live Room】——

　　 "I saw our Xia Guo's college team, Haicheng Jiaotong University."

　　 "Haicheng Jiaotong University has won the championship in the ACM competition, and more than once, he is our Xia Guo's biggest favorite to win the championship."

　　 "There are still Moscow State University and St. Petersburg State University this year. These two universities seem to be very strong in recent years."

"Indeed, in the past few years, Moscow State University and St. Petersburg State University have basically won the championship, but think about it, the team they used to compete in has already graduated? The new team can still take the championship. So as to defend the title?"

　　 "Hahaha, I saw our Northwest University of Science and Technology!"

　　 "To be honest, this year's Wucheng University of Arts and Sciences is indeed quite surprising, and it can actually get a place for the competition."

　　 "Students from Wucheng University of Arts and Sciences come to report, come on!"

　　 "I heard that Xu Bin from Wucheng University of Arts and Sciences is particularly good. He has been worshipped by many gods in the domestic computer circle."

　　 "Really? Is it so amazing?"

　　 "Everyone who has been in the computer circle should know that Xu Bin has an ID called "A Bin", which is called by the computer gods-the day does not give birth to me A Bin, the computer is like a long night!

　　 "So hanging?"

　　 "I am ignorant."

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

　　 "Similar to Apple? The plague is dead? An operating system like Android? Really or fake? It's such an exaggeration."

　　 "It's just a rumor. No one has seen A Bin's own operating system. Who can't brag about it."

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

　　 "Let’s wait and see, do you stay up late to watch the game tonight?"

　　 "Tomorrow Saturday, I must finish watching the game~www.wuxiaspot.com~ It's only about two o'clock after watching it, and the nightlife has officially started."

　　 "666, can you all stay up all night like this?"

　　 Xu Bin at this time obviously didn't know that he was being discussed variously by netizens watching the game in China.

　　 All his energy was used in the game.

　　 The ACM Competition Committee quickly determined that all 34 college teams were ready.

　　 Then began to give the first question.

　　 is [title A].

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

　　 The difficulty of the question, obviously starting from A, will become more and more difficult!

　　 After the first question was given, all the team members of the 34 colleges and universities participating teams immediately entered the state.

　　 is worthy of being a group of top university students majoring in computer science in the world.

　　 "Chen Jun, start to analyze the topic."

"Ok!"

　　 Chen Jun began to analyze [Topic A], and the way of analysis is also the most convenient way to communicate between him and Director Xu.

　　The purpose is to be more efficient for Xu Bin to start writing the problem-solving program based on the analysis of the problem.

　　In other words, Xu Bin and the others can analyze the questions and start answering them at the same time. This efficiency is not comparable to that of the average team!
