/**
  Problem Name : Minimum Number of Operations to Move All Balls to Each Box
  Problem URL : https://leetcode.com/problems/minimum-number-of-operations-to-move-all-balls-to-each-box/
  Description :
    You have n boxes. You are given a binary string boxes of length n, where boxes[i] is '0' if the ith box is empty, and '1' if it contains one ball.
    In one operation, you can move one ball from a box to an adjacent box. 
    Box i is adjacent to box j if abs(i - j) == 1. 
    Note that after doing so, there may be more than one ball in some boxes.
    Return an array answer of size n, where answer[i] is the minimum number of operations needed to move all 
    the balls to the ith box.
    Each answer[i] is calculated considering the initial state of the boxes.
