Oh boy, what a tedious one. I don't see any quick and easy optimization strategies here. the parsing is the most tedious part of this.

The first part went way more smoothly than I initially thought, by splitting the different steps into smaller pieces.

But the second part is a hard nut to crack. So many runtime/performance issues because the numbers are so "big" that my intail approach no longer works.

Last nut I finally cracked was in v28 by running the following on a powerful desktop machine for nearly an hour: deno run https://esm.town/v/karfau/aoc23_05?v=28 (that is the module URL) to get the correct solution.
