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, return the Hamming distance between them.

Example 1:

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.

Example 2:

Input: x = 3, y = 1
Output: 1

Constraints:

  • 0 <= x, y <= 231 - 1

SOLUTION:

class Solution:
    def hammingDistance(self, x: int, y: int) -> int:
        return "{:b}".format(x ^ y).count("1")
