Ugh, sat down and played with it, and now I remember why I gave up on SPOJ,
they tell you you got it wrong, but don't tell you why.

It usually boils down to obscure undocumented output formatting differences
(ie how much whitespace and where), but you can't tell whether it's due to
formatting error, or an actual wrong answer.

SPOJ needs to give feedback a la javabat.com

Also, codechef.com is basically SPOJ with a prettier interface, active
administration, and a community behind it. But I have had difficulty getting
Ruby to work there, in the past. Not sure why.
