Btw, maybe someone here knows how to make public playlist such that everyone (maybe with donates) will have an opportunity to automatically choose music to be played next?

Will there be a record?

I'd like to say, as a Chinese who lives in mainland, it's hard to access twitch.tv, but I can trace your submission on uoj.ac. Btw, do you know Sone1. If you need a description in English, please contact me. @300iq

Btw, do you want to try this problem? UOJ 417

poisoning problem recommand: uoj 319

uoj 403

                         uoj 398

                         bzoj 4023 (uoj 101) time limit on bzoj is insanely tight

                         bzoj 3710 5162(not hard but time limit is lnsanely tight)

                         bzoj 1154 bzoj 2840(test case is too weak q*n can pass)

                         bzoj 3948(I use bruteforce search get AC)

                         bzoj 5307

                         bzoj 3604

                         bzoj 4536

                         bzoj 4087 (I also use some bruteforce method AC welcom to hack)

when I remember other problems I'll go on to recommond

this is bzoj https://www.lydsy.com/JudgeOnline/problemset.php

now I'm writing uoj 398

I suggest UOJ 98

I like your taste of problems

The stream will continue today or tomorrow, now I am going to have a flight.

20:15 UTC+3 new stream, I will write the first sub-subtask of the k-FC problem.

It seems that now the current stream is lagging, so I will try to fix it for tomorrow.

So, because of these lags, I've finished earlier today and solved all test cases about the static tree. I hope, that tomorrow at the same time (or maybe a bit earlier) I will continue with writing dynamic tree (link-cut-memphis) to solve all subtasks with $$$k=0$$$.

Current code, but I think it will be useless for the future subtasks
