Hate (2)

Finally, I came to the "Battlefield" moment and went back and forth to Beijing for seven days. It was just for today's five hours... Tiangong is also regarded as beautiful. Compared with the previous two days, the temperature has increased a lot. I remember that the last day was a minimum of-2 degrees, yesterday was a zero degree, and today the lowest was 4 or 5 degrees. In fact, in the room, there is heating, and it doesn't matter how cold it is outside...

Just get up, eat, and then enter... With the countdown of 10 s, the game officially started. According to the Pre-competition plan, Lijun is responsible for the first three questions, me is responsible for the middle three questions, and Flybird is responsible for the last three questions. Even the three questions on this side are not difficult to understand. Basically, before Lijun started, I understood all the three questions in the middle. Unfortunately, I did not touch a simple question. In fact, it was also true, no team made two questions, and two or three teams made one question. In this process, Lijun is just a breakthrough. Due to the shortest of the C question, it is clear that I must first read the C question. After about 10 minutes, I also confirmed this, after a team passed C, N consecutive teams passed C. Obviously, we all know that C is a breakthrough point, and the referee also confirmed this point afterwards. Indeed, Lijun was disappointed, I made the first question in 15th, and ranked 15th at this time. Once I got an ac c, I was very excited. At this time, I thought that D would be easier. If string matching is related, I recommend Lijun to look at it. The question is meaningless. After that, he just went deep into the character string matching, after reading it for a while, there is no clue. At this time, several teams have given a or H. Obviously, these two questions must be a breakthrough. Just as Flybird saw h, after a rough thought, I started playing the game. Because the idea was not very clear, we had a lot of detours on question H, which complicated the situation. Flybird started to write, lijun continues to help with questions H. Now the two of them are reading questions H. Obviously, I have made another remark, and I have read the questions of the last three questions, I read three questions in the middle, but it's not very long. There is another team in the middle that has passed a or H. Obviously, H is not that complicated. This Lijun also thinks of it, And Flybird is also a method. After the game, the referee said the shortest path method, then, we must use the bow to consider the truth. So Flybird gave way and Lijun started writing the code. He was wondering if there were any situations where he would consider less test data, at this time, I also fully understood question A, which is obviously a search question. At this time, I didn't even realize that this should be a wide search, not a deep search, deep Search itself thinks it is better to write, that is, to write on paper... After several twists and turns, after Lijun and Flybird test the data, submit goes to H, good, once ac... After Question 2, ranking 21. Perhaps it is this pattern that has laid the foundation for the following bitter fruits ......

At this time, there are basically only three questions on the field, and occasionally several teams start to have four questions. Obviously, at this time, we still think that we are trying our best to do a, even writing, lijun is also reading a. Flybird started to look at the last question, because two teams passed. Shortly after, Lijun points out that this question is the same as that of a horse or a checkers. It is widely used for searching and recording the location of the door that passes through each point... I thought so too, so I told him to write it. I continued on the machine and added his ideas. When the basic framework is complete, it is called Lijun, and the code is called down. I printed the code and continued to modify the details. At this moment, it is also a wrong decision direction. I did not continue to change it after printing it out. I don't know when, everyone's ambition seems to be a little bigger, and I started to think about four questions, maybe I think Lijun should have been a must, because he has read a lot in searching, and he wrote similar checkers and checkers, it should also be a small case, so I will continue to read questions and think about solutions together with Flybird... This is the time that has passed. When we test the Lijun data, we find that the time is and only the last hour has passed. Then we submit the test data. This time, goddess Lucky did not come again, and the RTE error occurred... Everyone started to get a little anxious. All three people put it down and checked the last adjustment and changed it. They found the nemo location crossing the border error, so the error began to become wa, at this time, the time was so fast, and we were so excited and not calm, looking at a ranking of 28 that was not refreshed one hour before the competition, looking at the staff hanging up one by one balloon, the test was in a hurry... If Lijun was asked to calmly think about the problem, if he was asked to explain his solution to the general idea again, and if I was still quiet, I Would code the problem again, even if everyone is calm and don't be nervous, this is definitely not the case .....

However, this is the cool nature of the competition, or perhaps the attraction... In the last 20 minutes, I wrote a large test and the program started to pass. However, even if I knew that the test data was not passed, I still could not change it... First, the program is long, and second, everyone does not understand it very well. Please remind me when I look at the position of the Code. In the last five minutes, I still can't find it. No matter what, I will submit it first or I will have no chance. Obviously, there is basically no chance to pass this process... Last minute .. The countdown is 10 s .. At this time, Lijun said that he probably thought of a problem in only one place...

As a result, it is obviously 30 days away... Then we were so close to our vision of success that we could only get it by hand, but we didn't get anything in the end. This feeling is the most heartache. Maybe if the strength is so or worse, maybe you will feel better for other reasons...
