Solution: Hamming Distance

Explore how to compute the Hamming distance between two integers by identifying differing bit positions using XOR operation. Understand and implement Brian Kernighan's algorithm to count set bits efficiently, optimizing both time and space complexity for this bitwise manipulation problem.

We'll cover the following...

Statement

The Hamming distance between two integers is defined as the number of bit positions where the corresponding bits of the two numbers differ.

Given two integers x and y, your task is to find and return the Hamming distance between them.

Constraints:

  • 0≤0 \leq x, y ≤231−1\leq 2^{31} - 1 ...
