ACM one-year summary

The first is a brief history of freshman year, which is not the same as other people. I waited for my freshman year, so I just got in touch with my computer and started to download the program and install the system, I couldn't solve a small computer problem myself. Then I started a course called C language in my freshman year. I was so stupid that I didn't work hard at the time. I went to the machine room every week, the vast majority of the time is spent on learning mathematics, because I think I should transfer to a major to learn physics, and then I am decadent for nearly a year. In the next semester of freshman year, when the final exam is coming soon, I heard that the chicken brother was about to engage in ACM. I thought it was related to the fact that they were so active in thinking.

 

At the beginning, I brushed a lot of string questions (in fact, I used STL for a few lines of AC questions), thought I was very good, thought that the string was just this thing, and then began to search, at the beginning, I thought it was very difficult. What BFs, DFS, was so tall that it could finally be knocked out for a week, and it suddenly felt as long as ACM had returned BFs, DFS (search on a simple graph) is finished. Hehe later.

 

After that, I learned about the codeforces website. I heard that Daniel is working on it. Of course, I did what I wanted to do. I 've never missed it from 198 to 273, at first, I had only two questions, so even div2 had a very bad mix, but I believe that as long as I keep doing it, I can increase my score. Even so, I have never made up my questions. I have never played the blue name in the last 30 games, so I am very depressed!

 

Soon I arrived at the first neu monthly competition, and I was very depressed when I was abused. Later, I saw Jia, a freshman, completing questions after each competition, and instantly felt the gap. (It was really miserable to be abused by my freshman year.) Later, I made up all the questions that I could make up, but I could not make up the questions that I could make up. The results were indeed good and I had a lot of confidence, then, the scores of the new star game can still be felt (although there is a bare line tree, there is also a bare Fermat little ding did not come out ).

 

It was a bit of time later, because I wanted to engage in DP, but I never understood what kind of backpack, what Dag and so on, after looking for Tao juju to explain and draw a picture, I still don't understand this idea. (After all, I did not figure it), and then I put it on. Below I have made some simple graph theories, such as bad sets, dual-connectivity, strong connectivity, and shortest path. I still cannot figure it out, later, I felt like I couldn't go through it, so I almost went back to DP. At this time, I felt a bit familiar. I thought it was just to point the status, transfer to the edge and then divide the DFS and push the two ways to transfer, and then scroll the array, why can't I use DFS to understand it, and later I will be working on DP for a while, I had a lot of questions and it was winter vacation. During the holiday, I learned how to learn simple data structures, tree arrays, and KMP. The first two did not understand it at the time, then, during the winter vacation, CF still had this dish, and the score was just 1500 points. The monthly round of the winter vacation was also a bad hit.

 

I had no contact in advance when I joined the school, because I felt that no one was willing to team up with me. Fortunately, there was a one-month competition, I decided to make a good performance. The result was good and I got two FB. As a result, I contacted Cao Shen to form a team and successfully swindled Cao. Then, Cao Shen pulled Meng Juro to form a team. The provincial competition is coming soon. The provincial competition is very funny. youyoushui DP is not available, and graph theory is not available in some books, but we have a run of shit, the organizing committee has changed the standard for the lower-level competition in the province, and is really drunk by the number of questions. This saves us a lot of trouble. Next we had a few training sessions for the four provinces competition. To tell the truth, we were not doing well. Then we went to the arena and fell down unexpectedly. The main reason is that the competition was not good enough. During the competition, I was very excited and people were very upset. Although this problem may occur in the future, however, the subsequent competitions seem to be much better.

After the First World War of the four provinces, I was depressed again. Then, inspired by xlyle, I started to build a tree array (line, tree to linear, K ), simple data structures, such as line tree (range merging), character hash, and suffix array, have passed a few simple questions during the summer multi-school competition. During this period, I strengthened the DP. After all, I was the only one in the team to engage in the DP. Then, the CF score is 1700. It feels good.

Afterwards, the cyber competition relied on the xlyle's god to win many places for the school. We were sent to two sites, and then killed in various trainings. During this time, I made a decision on the tree, splay-tree, size-blance-tree, decision tree, KD-tree, and other magical data structures, but such as tree chain partitioning, I did not engage in anything as tall as the Chairman.

After the two stations came over, I took a copper and a iron. I still felt quite normal and had no regrets. (In fact, it is possible to get a silver in Anshan. But who blame me for not writing the evil simulation, tian Yi ). After Anshan came back, he played a TC div2 game and scored more than 160 million people. The first TC game became familiar with the environment. After that, Xi'an went smoothly to fight the iron.

 

What should I do next? I have a good idea. I should first understand my design patterns, and then develop python. I am asking you to give me some advice, finally, find a job (I don't want to work ).

 

ACM does not play, But TC and CF still need to be played. This is not time-consuming and there is no pressure. It only takes two hours for each competition and two hours for questions to be answered.

 

The above are some of my experiences. I am not good at communicating with others. I have made many detours on ACM by myself. I didn't know what to do at first, it even gave birth to the idea that you only need to do a good job in mathematics and give it to teammates. Next, let's talk about the problems in ACM.

It is undeniable that we are a weak school. The silver medal here is enough for you to be excited for a year. I know that only two teams have won the silver medal and no more than three teams. There are many reasons for this situation, but the vast majority of the reasons are ourselves, and I am also very good at cooking, Which is undeniable. However, I believe that the environment will slow down when cainiao and Daniel increase. First of all, we have a monthly round, which is only once a month. During this period, we want to do what we want. This has many advantages but disadvantages. I personally think that the CF competition can be used for weekly competition. It does not consume too much training time, but also improves the feeling during the competition, as well as the brain and hand speed. (It is really not scientific to see that many of the sophomores do not engage in CF.) then there is a reasonable reward system. That's all...
