Day 11: Cosmic Expansion [AOC2023 Python]
For Advent of Code 2023 Day 11, I get a map of galaxies in space. I need to get the manhattan distance between each pair and sum that. The twist is that any empty row or empty column counts for more than one space. In part 1, it's double. In part 2, it's a millions times!
