Hamming Distance
Easy
Topics
The Hamming distance between two integers is the number of positions at which the corresponding bits differ. Given integers a and b, return their Hamming distance.
Example 1
Input: a = 1, b = 4 Output: 2 Explanation: 0001 vs 0100 differ in two bits.
Example 2
Input: a = 3, b = 1 Output: 1
Constraints
- 0 <= a, b <= 2^31 - 1
