Can anyone name some red-coder(s) who write good explanatory codes and participates frequently in contests.

Idea is I want someone whose code I can read after contests because I barely understand editorials of problems > Div 1 B.

Hello everyone!

I feel i am bit bad towards mathematical side. I want to solve a lot of problems on DP and recurrences. And various techniques used in solving DP problems (DP optimizations). Where should I go about? From where do I get the specific set of problems to solve.

Thanks, any help will be appreciated!
