Solution: Hamming Distance

Explore how to solve the Hamming distance problem by applying bitwise manipulation techniques. Learn to use XOR to identify differing bits and apply Brian Kernighan's algorithm to count them, enhancing your skills in efficient bit-level coding problems.

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 ...
