https://adventofcode.com/2023/day/5 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.

https://adventofcode.com/2023/day/8 the script times out on val.town, so I ran it with deno on my machine for some mintes. By running deno run https://esm.town/v/karfau/aoc23_08 | grep z I observed a repeating pattern in the output... each "track" was reaching the same position over and over again, but not on the same lines. I dumped the beginning of the output into a text file, opened it to look at the patterns and confirmed that each "track" had a fixed frequency for each position ending on a Z. so I took the "step"(+1 because it's zero based) and checked the primes each of them contains, to get the correct input. I calculated that with a calculator and copied in the number.

Script

```bash

deno run https://esm.town/v/karfau/aoc23_08 | grep z

I observed a repeating pattern in the output...
