Comparing two integers without any comparison

Question

Is it possible to find the greatest of two integers without any comparison? I found some solutions:

if(!(a/b)) // if a is less than b then division result          


        

Answer 1

char c;
c=0x3D + (!(b/a) && (a-b)) - (!(a/b) && (a-b));
printf("a %c b",c);
