Codeforces Round #753 (Div. 3) Editorial

Revision en1, by doreshnikov, 2021-11-04 03:09:49

Short information

Sorry for another delayed editorial, I know I promised that it will come out sooner the previous time, but I wasn't feeling well today, so the work was slower than usual.

About problem F:

I am once again sorry for the inconveniences caused by tight ML in this problem. It was not the intended behavior since we relied too much on the main solution and didn't assume most of the solutions using DFS will fail. In this editorial I attach the code of the main solution that we expected from the beginning, it uses ~75MB of memory.

I guess, Div. 3 Rounds are not only for participants to learn but also for authors. I'll try not to repeat the same mistakes the next time :) Thanks to everyone for participating and hope to see you again!
