Hello,
Does anyone know how to create Codeforces like interactive problem in cms? What I mean codeforces like is no header file, just communicate with stdin/stdout, but I've never seen anything like this from other olympiads.
Thanks.

Hello
I want to improve from 2500 to 2800 or 3000 (if possible). What kind of method do you use to improve from here? I feel like I'm stuck at my current level, but I don't know what exactly I need to do. Any advice?
