Leetcode Problem 477. Total Hamming Distance

477. Total Hamming Distance

Leetcode Solutions

Approach # Loop over the bits!

  1. Initialize a variable total to store the total Hamming distance.
  2. Loop over each bit position (from 0 to 31, since the problem statement mentions 32-bit integers).
  3. For each bit position, initialize a count k to 0.
  4. Loop over all numbers in the array nums.
  5. If the current bit is set in the number, increment k.
  6. Calculate the number of pairs with differing bits at this position as k * (n - k).
  7. Add this count to total.
  8. Return total as the result.
