477 - Total Hamming Distance.
Medium
The Hamming distance between two integers is the number of positions at which the corresponding bits are different.
Given an integer array nums
, return the sum of Hamming distances between all the pairs of the integers in nums
.
Example 1:
Input: nums = [4,14,2]
Output: 6
Explanation: In binary representation, the 4 is 0100, 14 is 1110, and 2 is 0010 (just showing the four bits relevant in this case). The answer will be: HammingDistance(4, 14) + HammingDistance(4, 2) + HammingDistance(14, 2) = 2 + 2 + 2 = 6.
Example 2:
Input: nums = [4,14,4]
Output: 4
Constraints:
1 <= nums.length <= 104
0 <= nums[i] <= 109
- The answer for the given input will fit in a 32-bit integer.
