My learning note on AGC061C based on Little09's (Simplified) Chinese Blog

Revision en2, by CristianoPenaldo, 2023-02-15 14:10:18

I admit that AGC061C is too hard for me, and I don't even understand its official editorial. Today I see a Luogu blog with a very clear idea on this problem. I would like to share it to you.
