Before I knew it, it was summer vacation. I participated in a special training in Hangzhou for the past two days. I was bored in class and thought to add it.
emmm, last year the school competed at Peking University, but this year it is at Beijing Union University. I am still a little disappointed and have no time to go.
The two teachers who accompanied him were very easy-going. One of them had a unique temperament and a childlike innocence. He had the feeling of going out to play with junior high school students. It was very interesting.
It takes only six hours to travel from Anhui to Beijing by bullet train. As a poor child, the fare and hotel accommodation fees are very painful. The single person is nearly 1,000 (although it is from the school 
). The departure will be at 7:00 in the morning on May 25th and 2:00 in the afternoon. arrive. The weather in Beijing was slightly hot at noon, about 30°, but it was still possible to go out for a walk, much better than the sunshine in July today. After the rest, I went to the United University in the afternoon to see the examination room. It was past five o’clock and the weather was pleasant at 26°. It happened that the Bird’s Nest and the Water Cube were very close, so I didn’t go back to the hotel. The room is spectacular, the night view is better, and it is very temperamental.
It was said that the algorithm was well prepared two days before the game, but in fact, I didn’t see much. However, for a game with a lot of water such as the Blue Bridge Cup, the assault is still very effective. At least with experience, I can’t do it. How many points can you get.
Over the past years, Group A has competed in the morning, and Group B has competed in the afternoon. On the morning of the 26th, I slept well, and then casually looked at the question types in 2015, 2016, and 2017. C++B group, basically violent loop and dfs are compulsory questions. Dynamic programming, divide and conquer, and geometry are also occasionally tested. Unfortunately, as the last person in the team, the scattered time for learning algorithms is not enough for a month, and the level is really insufficient. In addition, the overall strength of colleges and universities in Anhui is relatively low compared to other provinces, and the goal is just to get into the second country by luck, because it depends on the question and the situation of winning questions in previous years. It can be National Three, so the mentality is guaranteed by National Three.
When I went to the exam room in the afternoon, group A had just finished the exam at 1:00, and then group B took the exam at 2-6:00. Basically, they sat separately in the same exam room. As for the questions, they were almost as expected. The thinking is still ok, the DE questions can barely be solved, but I don’t know how many I can get right. I have no experience with the F questions, and I have passed several sets of test data.
According to my personal situation and experience, the order of my questions is ACDEFB. . . Filling the blanks in question C is more difficult than expected. The difficulty is not logic, but thinking. At that time, I didn’t expect that API and bit operations could solve the loop in one line of code, so after wandering for a long time, I could only write a parenthesis operation myself. The data should be cool. It's a pity that it was question B. The result was filled in the blanks. Only later did I realize that I had had a similar experience before. If I hadn't given up on it from the beginning, I might have solved it by leaving more time for it.
Four hours is still not enough to solve it in the end, but in the end, it is a word dish. Even if you listen to the big guys in your peers and talk about the answer, and repeat it again, some questions still can't be solved.
After the game at 6 o’clock, I went back to the hotel, had something to eat, and then took the subway to Tiananmen Square with the three children’s shoes of the sophomore year. The juniors and seniors didn’t go there. Although I really wanted to go to the Forbidden City, it was not open at night. . Even at night, there are still many people in Tiananmen. After queuing up to go through the security check, the soldiers standing guard stood straight, especially the one in front of Tiananmen Square, who remained motionless for a long time. Although I had the idea of staying at Tiananmen and waiting for the sunrise to go in the next day, I went back to the hotel anyway.
Because the original plan was for the morning ceremony on the 27th, I booked the ticket for the afternoon, but unfortunately those activities were all cancelled by the organizer. The house attribute played a role, and I didn't play much, so I went to the station after 10 o'clock, and the results came out at about 12 o'clock noon. It's a pity, it's only the third country. In the long list, I am a few people away from the last place in the second country. . . As long as you are a little more correct, you can get the second country, I feel a little careful and tired.
However, to sum up, to borrow the words of a senior: Don't let the competition affect the mood of the tour. It is worth mentioning that I happened to lose my USB flash drive, and this time I gave a 32G USB flash drive, which is very small. It can be used for both Android phones and computers. Although it has a 2.0 interface, it is very convenient, and cuteness is justice 
. The quality of the competition ballpoint pen is poor, the bread tastes average, and I don't like to drink milk, but after all, it is a free product, so let's give it a five-star praise. Maybe I can go again next year in the third, fifth, and sixth year. The weak chickens don't dare to choose the A group. The goal is to win the B group for the school and myself.
Interesting words to repeat, don't let the game affect the mood of the tour.
