1818. Minimum Absolute Sum Difference

Leetcode Solutions

Binary Search for Minimizing Absolute Sum Difference

  1. Calculate the initial absolute sum difference between nums1 and nums2.
  2. Clone nums1 and sort the cloned array.
  3. Initialize variables to keep track of the sum of differences and the maximum reduction possible.
  4. Iterate through each element in nums2.
  5. For each element, find the closest element in the sorted nums1 using binary search.
  6. Calculate the potential reduction in the absolute sum difference if we were to replace the current element in nums1 with the closest element found.
  7. Update the maximum reduction if the current potential reduction is greater.
  8. After iterating through all elements, calculate the minimum absolute sum difference by subtracting the maximum reduction from the initial sum.
  9. Return the result modulo 10^9 + 7.
