Hi Codeforces, when I go to any competition (for example, http://codeforces.net/contest/786) it seems that it only shows most recent submissions (up to 22th October this year). The same happens with any profile, only most recent submissions. Can somebody take a look at this? Best regards, 156302

Hi, I'm having trouble understanding the solution of the following problem http://codeforces.net/contest/802/problem/I using Suffix Array, that is, the first solution in Editorial. Can someone more familiar with Suffix Array explain the solution to me?

Why is submissions page blocked by administrator? It is blocked for all the accounts
