1769. Minimum Number of Operations to Move All Balls to Each Box

Leetcode Solutions

Two-Pass Cumulative Sum Approach

  1. Initialize variables left_operations and right_operations to 0, and left_count and right_count to 0. These will keep track of the cumulative operations and the number of balls to the left and right of the current index, respectively.
  2. Create an array answer of the same length as boxes to store the result.
  3. Iterate over boxes from left to right. For each box, add left_operations to answer[i], then update left_count and left_operations based on whether the current box contains a ball.
  4. Reset right_operations and right_count to 0.
  5. Iterate over boxes from right to left. For each box, add right_operations to answer[i], then update right_count and right_operations based on whether the current box contains a ball.
  6. Return the answer array.
