2602. Minimum Operations to Make All Array Elements Equal

Leetcode Solutions

Prefix & Suffix Sum with Binary Search

  1. Sort the nums array.
  2. Calculate the prefix sum array ps such that ps[i] is the sum of the first i elements of nums.
  3. Calculate the suffix sum array ss such that ss[i] is the sum of the elements from i to the end of nums.
  4. For each query value q in queries: a. Use binary search to find the smallest index pos where nums[pos] >= q. b. Calculate the number of operations needed to make all elements before pos equal to q using the prefix sum. c. Calculate the number of operations needed to make all elements from pos onwards equal to q using the suffix sum. d. Add the results from steps b and c to get the total number of operations for the query.
  5. Return the array of total operations for each query.
