5th-July-Hamming-Distance.cpp

Solution:
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 n = x^y;
        int count =0;
        while(n>0)
        {
            n = n&(n-1);
            count++;
        }
        return count;
    }
};
