Hi, everyone!

Recently I solved problems from Codeforces Beta Round #5 and when I could'n solve problem D, I wanted to browse someone else's solution, but I could'n do it. Competitors' solutions are closed, and I can't look it.

Moreover, I can't look every solutions before Codeforces Round #100. Links are inactive. Like this...

The exception is problems, that I have solved.

After Codeforces Round #100 I can look every solutions.

I would like to know, is everyone have a such trouble?

Sorry for my bad English :)
