Comparing two numbers x,y; if x>y I return 1, else return 0. I am trying to do this using only bitwise operators such as >> << ~ ! & | ^ +. So far I got this: int greaterThan(int x,int y) { return ((~(x-y))>>31); } So if x-y is negative, the most significant bit would be a 1. So I negate it to get a 0 and shift it so that it returns...
