Solution: Hamming Distance

Understand how to calculate the Hamming distance by isolating differing bits between two integers using XOR. Learn to count set bits efficiently with Brian Kernighan's technique, optimizing for time and space complexity.

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 ...
