Programming (fun):

The following fully functional 'chromosome-shaped' program is one of the winners of 2014 International Obfuscated C Code Contest . What does it do?

#include <stdio.h> #define TA q=/*XYXY*/ #define/*X YXY*/CG r= void p(int n,int c){; for(;n--;) putchar(c) #define Y( z)d;d=c++\ %2<1?x=x*4 +z,c%8>5?\ x=x?p(1,x), 0:x:0:0;d= #define/*X YX*/C Y(1) #define/*X YX*/G Y(2) ;}int(*f)( void),d,c, #define/*X YX*/A Y(0) #define/*XY*/AT int\ m(void/**/){d= #define/*XYX*/T Y(3) #define GC d; return\ 0;}int(*f) (void )=m; x,q,r; int main(){if( f)f();else {for(puts( "#include" "\40\"pro\ g.c\"\n\n \101T"+0); d=!d?x=(x= getchar()) <0?0:x,8*8 :d,TA++c%8 ,TA(1+7*q- q*q)/3,r=c *15-c*c-36 ,p(r<0?!q+ 4:r/6+!q+4 ,32),q||x; c%=16)q?p( 1,"ACGT"[x /d&3]),p(q ,126),p(1, "TGCA"[x/d &3]),d/=4, p(001,10): puts(c%8?\ "CG":"TA") ;puts("GC" );}return 0;}/**/

Hints

Copy and save the code of the program to a file, say prog.c
Compile the code as usual:
```
clang -Wall prog.c -o prog
```
Run the program as following:
```
echo 12345 | ./prog
```
