Leetcode 2141: Maximum Running Time of N Computers

In this problem, we try to figure out how long we can run n computers using a list of batteries. We have to use n different batteries at any moment and switching them can be done any time (as long as it is a whole minute). Each battery has a set number of minutes that it can be used for.

You have n computers. You are given the integer n and a 0-indexed integer array batteries where the ith battery can run a computer for batteries[i] minutes. You are interested in running all n computers simultaneously using the given batteries.
Initially, you…
