AoC 2022 Day 11: Monkeyinator

Source: Monkey in the Middle

Part 1

Simulate a collection of ‘monkeys’. Each monkey will have a number of items which it will then apply a mathematical operation to, then always divide by 3, then test divisibility to pass to one of two other monkeys. Return as answer the product of the two highest number of times a monkey applies it’s main function to individual items after 20 steps.

Note: Monkeys will always be evaluated in order (so monkey 1 will evaluate any items passed by monkey 0 again in the same round).
