HAMMING DISTANCE

The Hamming distance between two integers is the number of positions at which the corresponding bits are different.

Given two integers x and y, calculate the Hamming distance.

Note:

0 ≤ x, y < 231.

Example:

Input: x = 1, y = 4

Output: 2

Explanation:
1   (0 0 0 1)
4   (0 1 0 0)

The above arrows point to positions where the corresponding bits are different.

Solution:

class Solution {
public:
    int hammingDistance(int x, int y) {
        int count=0;
        bitset<32>binary1(x);bitset<32>binary2(y);
        for(int i=0;i<32;i++)if(binary1[i]!=binary2[i])count++;
        return count;
    }
};
