I just completed "Supply Stacks" - Day 5 - Advent of Code 2022 #AdventOfCode https://adventofcode.com/2022/day/5

When I read it on my phone in the morning, I thought I'm not gonna solve it today, but it was interesting, actually. Any ideas on how to import the stacks from the file? I just manually hardcoded them in the code, but that would be far from optimal in a case with 100 stacks.
