唉，我就料到会有一群人点 downvote 的。不知道你们瞎点 downvote 干什么。果然 CF 的评价是随机的。

或者说，一个简单的观察你们点什么 downvote？是不是被 AI 吊锤了心里不爽啊。

我就用中文。你们爱看不看。

In fact, I found that someone in Linux Do community has already built an agent with Gemini 3 flash, which can AK global round 31.

You're not wrong. There's too many classical tricks or templates (even problems already appeared on other onlinejudges) in ABC. It's bad for the quality of contests.

good round. E is simple, but F seems hard and I don't know how to solve it.

thanks for reply

I agree with you. I think D is good, but E is rubbish(it's too classical and boring). What's more, the difficulty gap between E and F is too big.

Could the new judging system be opened for testing before the next competition starts? I don't want to face a completely new and unfamiliar system when I get to the ABC contest.

By the way, long live chez scheme!

I agree with you, but I can't imagine such a person who can use just 4 minutes to solve F. In fact, It seems that I used 15 minutes.

The quality of problem E is very high. Problem F is too formulaic and can be solved with a simple tree decomposition, or even without it, just using DFS order + Fenwick tree.

It's a decent contest, Problem D is quite valuable, but Problems E and F are too straightforward, and Problem F is purely a coding volume question.

EvenImage said while teaching us that f is very simple, while e is much hard (the pass rate seems to support his view)

For CNOIers, this is unimaginable.

Is this the same as the "zkw segment tree"?
