C code required

/*
* isGreater - if x > y then return 1, else return 0
* Example: isGreater(4,5) = 0, isGreater(5,4) = 1
* Legal ops: ! ~ & ^ | + << >>

Answer 1

#include <stdio.h>

int isGreater(int x, int y) {

int negateAdd = ~x + 1;

int addSum = y + negateAdd;

addSum = addSum >> 31;

return addSum&1;

}

int main(void) {

printf("%d\n", isGreater(4, 5));

printf("%d\n", isGreater(5, 4));

printf("%d\n", isGreater(-5, 6));

printf("%d\n", isGreater(6, -5));

printf("%d\n", isGreater(-4, -5));

printf("%d\n", isGreater(15, 4));

printf("%d\n", isGreater(5, -6));

return 0;

}
