Question

Positive or negative number using bitwise operators

Answer 1

Explanation:

When we do a -n>>31, if it is a positive number then it will return -1 as we are doing -n>>31 and the vice versa when we do for a negative number. So we know it returns 0 when it is a negative number, it returns 1 when it is zero, returns 2 when it is a positive number.
