I tried solving problem B of Codeforces Beta Round 2 — Problem B: The least round way.
It showed WA and I tried to see the test case for which I got WA. But I am not able to see my solution. In fact solutions of others are also not visible.
When I tried to open submission directly by link:
it showed: You are not allowed to view this page.
What is causing this problem? Can we fix this?
