• Result checker seems to get stuck

 

Hi! I think I solved this task correctly, but the result checker gets stuck in test 2/2 and just stays there. I'm quite sure that my solution doesn't contain any infinite loops and though I have been wrong a few uninportant times in the past, I still think that this must be some kind of bug...
