Conclusion of the first team competition

Icepoint fought for the first time yesterday and lost the first battle! Start to see a line segment tree question, DB just one day before, knock on 1A. I checked a physics question with Gx and started to analyze the error process. We put it down three times and put it down! Later, DB showed me a greedy question. The tangle was that we didn't come up with a good greedy strategy, so we had to put it down first. GX is working on a big number question. enumeration is used... I'm dizzy, decisive TLE. Then I went to the question and used log () or TLE... Finally, I thought this question was very watery. The question is thrown! Sort out your ideas and click 3A. At this time, the two of them are doing another few questions, but the meaning of the questions is hard to understand and the ideas are very watery. I came back to read the greedy question and thought about it for a long time. I did not think about the determination 1A. This is DB's penultimate question a. The two of them started to read a binary question and threw it to me a question about very long, later I looked at the figure given by the question. Isn't this the shortest path ?! Decisive Prim, 1a. Finally, I had a hard time with the database. The tragedy is that the physical process has not been simulated. In this way, a has five questions in total.

In general, the first team was a little messy and nervous. After the question is not divided, it is messy to do it later. Lessons learned and make persistent efforts! Icepoint, come on!
