My code works on windows cmd but not here?

This problem is using Windows line endings. I apologise for the inconvenience.

In the future, please try using raw_input().strip(). If adding strip() makes it work, then please leave a note in the comments and we'll try to fix it ASAP.

Still not fixed. This is a serious issue and really annoying, especially when doing byte-level manipulations. I get a WA with no indication at all as to what is wrong, and I can only consider myself fortunate that I saw the comment before I started debugging.
