/**
 * 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
