原文说明：Here's a nice challange for people who THINK they know how to read other people's code...
It's a small C program. I know, I know, it doesn't look like it's gonna get compiled, but believe me, it does. Try to guess this program's output, then try to run it. You'll be amazed to see what it does!
C语言版的挑战：
#include <stdio.h>
main(t,_,a)char *a;{return!0<t?t<3?main(-79,-13,a+main(-87,1-_,
main(-86,0,a+1)+a)):1,t<_?main(t+1,_,a):3,main(-94,-27+t,a)&&t==2?_<13?
