Well I have the same feeling. Though I didn't take part in it, after viewing these problems I felt superised that I can find out how to solve E so easily.

That's really a good beginning. Hope Luogu become better and better!

You can see that there are hundreds or even thousands of replies about "qp" or "zc" in some discussions in Luogu.

"qp" "zc" are not bad, but it will take up too much space if so many people send it here.

https://oier.baoshuo.dev/oier/82575 is that you? You can get such a high score in Senior Group when you are in Grade 8! I can never do it.

Don't post meaningless messages here. You can speak Chinese in "Talks" module.

The round started at 20:05(UTC+8), That's great. But today is Monday. Because of that, I can't participate this contest.

I know that some Chinese people hold this contest. But as a Chinese middle student, I don't think it's a good time to start the contest. Chinese students especially high school students have nearly no time to participate the contest on Mondays. I'm just in Grade 7 but I have too much homework to do. I usually finish my homework after 10:30 p.m.

I think you are joking too.

This round is hard for me.

Yeah, but I did it by myself. I used O(t \times log2(x)) algorithm. If it becomes unrated, I will lose 300~400 ratings.

I hope so.

That's too slow. Why not start the system test?

Well, I practiced segment tree when I was in grade 6. (I was not good at it at that time, and now I am still not good at it.)

I cleared Bronze with 500 or 600 CF rating, but CF and USACO problems are different,You need to understand.
