I am trying to solve Problem M: Counting Marbles. I am writing an editorial in case somebody might need it after me, and I am also trying to ask for help in spotting the error in my code.

Editorial:
We are essentially trying to write the smallest base-365 number with the marbles. So we must minimize the earlier digits as much as possible.

Use a priority queue with the tops of the stack, and whenever you use a marble, remove it from the priority queue and put the next element in the queue instead. Please see my solution for one such implementation.

Help: My solution is able to run on the sample test cases, but I'm getting WA (could somebody take a look at this)?
