In 2020/05/24 14:00 KST, I will stream solving 全国統一プログラミング王決定戦本戦.
I'll also experiment with my new tablets, so there will be some explanation of my thinking process.
Even if you can't read Japanese, don't worry. I can't read it either, and I'll have a hard time with the translator too.
The stream will end if I solve everything or if it's too late.
Stream link is https://www.twitch.tv/gs14004 as usual.
See you!
Started!
Thanks for watching! The stream is finished. I solved first 7 problems in about 2hr, but couldn't get the last problem for several hours.
After building a nice flow graph, we need to do something similar to Codechef NOV19 PBOXES. I also used a lot of time for that problem before, but I don't know how to solve it. I have to do lazy propagation and maintain some simple DP, but it seems range removal changes DP structure heavily. I'll think about it more later.
