2448. Minimum Cost to Make Array Equal

Leetcode Solutions

Prefix Sum Approach

  1. Pair each nums[i] with its corresponding cost[i] and sort the pairs based on the nums values.
  2. Create a prefix sum array of the costs to efficiently calculate the cumulative cost.
  3. Initialize totalCost with the cost of making all elements equal to the smallest value in nums.
  4. Iterate through the sorted nums, updating totalCost for each unique value by considering the difference in cost from the previous value.
  5. Keep track of the minimum totalCost encountered during the iteration.
  6. Return the minimum totalCost as the answer.
