Note: There is a single compile-time warning when compiled with -Wall; if this bothers you, you can place 10 bytes of bloat in the form of return 0; at the end of the program (before the final })

Since you are a Slashdot user, I am sure you can figure out exactly what the above code does without needing anything wimpy like documentation.
