Hello!

My team and I are preparing for the ACM ICPC world finals. There are two ICPC preparation camps this winter, roughly around the same time: The camp at Petrozavodsk, and a training camp at Barcelona

We had it in our minds to go to Petrozavodsk. We really enjoy the problems that come out of that camp. But this camp in Barcelona seems interesting as well, and seems to also be under the guidance of big names in the competitive programming community.

So I'd like to get the opinion of people who are familiar with both these camps. What would you recommend? We're interested in what would be the most beneficial for our training for the world finals, so basically, we're looking for the place with the best problems and editorials, and we don't care much about things like bonus activities.

Thanks in advance!

Hey guys ! I kind of need your help to understand why I can't get past a test on this problem:

http://codeforces.com/contest/611/problem/H

It fails on test 3. I've extracted that test, ran it with my solution and to me it seems nothing is wrong. The checker reports "Graph is not connected", which is weird because if you check the output, it IS connected. Every node is connected to either node 1 or node 10, and nodes 1 and 10 are connected with each other.

My solution:
