What does this code do?

[Kenny McCormack]

Get off your friggin' high horse, mister perfect-maths-wizard. You have
not the slightest idea how I tested your program wand why I could not be
arsed to do more of an effort. But since you asked for it, I'll tell you
now: I couldn't be arsed because it was crappy code, used in a crappy
puzzle, by a crappy programmer who should have known better than to
consider that crap even remotely acceptable. And in the future, I won't
even be making what little effort I have this time; your programming
inadequacy is not worth it.
