Hi everyone, I have seen a lot of gold silver medalists codeforces acc. And I understand that they just use codeforces as contest tool (I mean they not train with codeforces problems). Then I searched how they or from where they actually train, and I found out that they train from their own private camps. Then I searched contests, problems of their camps, but I did not find any of them. If you have link or problems of these camps, would you mind it to share ???
