Solution: Hamming Distance

Understand how to find the Hamming distance between two integers by identifying differing bit positions through XOR operation. Learn to count set bits efficiently with Brian Kernighan's algorithm, improving your problem-solving skills in bitwise manipulation. This lesson covers the solution steps, code, and complexity analysis to deepen your understanding of this common coding interview pattern.

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:

  • 00 \leq x, y 2311\leq 2^{31} - 1 ...
