Hello Friends, Codeforces has done many things right, that other OJs lack. The problem number is also conveying the information of difficulty i.e. A, B are easy, C is medium, D and E are hard. Also it is prefixed with the contest-url id , making it easy to navigate to the problem (and all the things linked to it like editorial, standings, etc).

Feature Request: It would be more beneficial if somehow the problem id also displayed which div it belongs to, since Div1 A is pretty hard as compared to Div2 A, but there is no way of knowing. The is good majority of people that'll always be in Div2(since beginners start from here).

Suggesstion: If possible, we can append 'D2' or 'D1' to respective problem ids.

Please let me know your thoughts, and if possible please make it reach to MikeMirzayanov :)
