Hoj -- monthly09.03, monthly09.04! Miserable !!!

The competition in the lake was over in the last three or three months. I felt very disappointed when I lost the game. I had a total of three questions. I am so sorry to say that I remember there was no pressure during the first monthly competition, it is just to open your eyes and do two things. Now the food is getting better. The question is not very difficult, or the foundation is not good, and I don't want to do water questions, which leads to the tragic conclusion of today. When I first got the question in the March round, I read the first question and thought it was Dijkstra. I tried to find the number of short-circuited items, I used DFS to find the number of paths (Da Niu moxiao). I had been using TLE and couldn't help it. I looked at rank and found that there were a lot of people with questions E, so I went to the question. The question is not hard, I wrote it, not a runtime error or wrong. At this time, I was very depressed. I looked at another question that I had encountered. It was a recursive question. I thought about it and wrote it, submit, runtime error speechless, check, submit n times can not pass, three hours more than not open, do not mind to read other questions, it has been stuck there, after a moment of calm, I thought about it again, and found that the formula can be obtained through recursion. It was very easy to modify and submit it. Finally, I got an ACCEPT, followed by another question a and question E, question A cannot be answered, and the time is up.

After discussion, I found that the proposal for question e was wrong, and question a was Dijkstra. I just needed to modify it. I wanted to practice well. The next month's competition will be better.

A month was really fast. I felt that I had not done many questions, and I had deepened some algorithms. The monthly round in April was just over again. This question was a little more difficult. I read the question once I got the question, first of all, I had a simulated question. I had been thinking about two mathematical questions, that is, I couldn't push the formula. I had to look at a graphic topic and read the question for a long time. I didn't understand the question very well and did not dare to write it, there were no other questions in the back. I had to push the math questions for a long time. It seemed that I was correct, but I found that the data calculation was too large, I couldn't come up with other methods. Later I went to look at a probability question. It didn't seem very difficult. I had no idea. I kept stuck, and there was only one hour left. I couldn't do it either, let's look at the following questions. One question is multi-level sorting. If you think about it, you can write it and change it after writing it. After the change, check the results with the question, I found that the results were aligned to the right, but I wanted to align to the left. I didn't know how to change it, and the game was nearing completion. The final result was only.

The two miserable lessons have clearly led me to realize that my foundation is poor, mainly because I do not like water-based questions, and I have made too few questions and practiced too little, in addition, during the competition, my own psychology was unstable, and I was in a hurry when I was doing the exercises. I was not careful when I was reading the questions and thought about the questions. I should never think about it before I thought about it completely.

I'm going to take the test tomorrow. I'm in a bad mood. I can't read any books. I came back and wrote something. May Day is approaching. I don't want to go out to play. I have to do some things over the past few days. A school competition is a teaming competition next month. I hope Snowbirds can do better!
