It would be best if you would post the code, if it isn't too long.
I want to prevent that people are able to copy+paste solutions from others.

With or without the solution as number? I mean one could also post code that theoretically will solve the problem but practically runs an eternity :D Nice Problem btw

Edit: Dont want to offend you or anything, just dont want to ruin the contest by posting the solution in the wrong way.

with the solution of course. The code is just to prevent copy/paste and maybe so that I can help you if you made a mistake.
