Gostei, primeira que fiz em uma linha.

spoiler flag, plz...

I am having this exact same issue in Python 3.4.3.

Please which language?

I have one error in the submit but it doesn't tell me what that might be on the listing:

I would love to correct it, but don't have anything to look at...

Having an issue with the -1 result in Ruby. When ever I return -1 h == window or h < window it times out. But when I return the values h, window it will show 10, 10 or even if I put return -2, it will return -2 and not time out... Really weird, otherwise I would of enjoyed this kata.
