Code off

Welcome to the first annual /prog/ Code off !

The language will be C.

Compeptitors include (in no particular order):

Mr. Ribs
Xarn
FV
Anonymous
W. T. Snacks

Rumor has it, that there may be a special guest appearance from either The Sussman or
Leah Culver.

What's the point of this, you ask?

It's to determine who is an EXPERT PROGRAMMER.

Marking criteria:

Optimization
Elegance

Bonus marks:
indentation

Good luck!
