I'd like to know, what's the most memorable contest you've participated in? It could be due to theme, the problems or some other crazy thing. It doesn't have to be CodeForces, but if you could link it, that would be great.
It's pretty hard to remember contests from a year back... and yet the One Punch Man one was cool, and I remember Round #361 (Div. 2) by I_Love_Tina gave me a serious I_Love_Tina check (excuse me while I excuse myself now).
Also I'm 7-8% weeb so if there are other anime-themed problems that would be cool. I know there are a few on DM:OJ because the head problemsetters for a year were all huge anime'ers who watched some Grisaia no Kajitsu "Special" Episode for a whole hour right before a contest, at the contest venue... but that's another story *cough* FatalEagle *cough*.
So I'd love to hear your most memorable contest or favorite problems.
I slept at 6AM so I'm sorry if this post is extra cancerous to read.
