461 - Hamming Distance\.
Easy
The [Hamming distance](https://en.wikipedia.org/wiki/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
