vovuh it has been more than 15 days since we had the last div3 contest.

When can we expect the next div3 contest?

Hi, I am having a hard time debugging this very solution of mine.

It would be of great help if someone could help me by pointing out the mistake in my code. The code fails at test case 57 which is too large.
