korn.c is the "Best One Liner" winner of the 1987 International Obfuscated C Code Contest, by David Korn (yes, the author of the Korn Shell).

korn.hint, as the name implies, offers some hints.

A commenter on Stack Overflow asked for some clarification. I didn't want to post spoilers on the site, so I'm posting them here instead. If you haven't already (and if you're familiar with the rules of C) I encourage you to study the program for a while first.

Here's the code:

""" Convert values between RGB hex codes and xterm-256 color codes.

Nice long listing of all 256 colors and their codes. Useful for
developing console color themes, or even script output schemes.
