Each row below are the stacks of water bottles with their respective heights(n)

1. | 2 | 1 | 3 | 3 | 3 | 2 | 3 |

2. | 2 | 2 | 2 | 2 | 3 | 4 |

3. | 1 | 1 | 3 | 4 | 3 | 5 | 1 | 4 |

The rightmost element shows the top of the stack. Adding up the heights of the bottles on a stack will give you the overall height of the stack. You can pop the bottles from each stack any number of times to change the height of the stack.

Determine the maximum height of each stack where all of the three stacks are equal in terms of height.
