If you search interesting problems for practice, we invite you for Everyday Contests!
We will make contests everyday. Contests will start on 17:35 UTC +3. Except: We will not make contests in days when our contests will clash official Codeforces rounds.
You will be given 4-6 problems and 2 hours for solve them. Contest will be held on extended ICPC rules. After every contests would be editorials.

Good luck! :) ContestEveryday
