Create the file `input.txt` and paste aoc puzzle input

Run part A or B

`bun run a.ts`

## 3. Puzzle descriptions

1. 💫️🌑️🌑️🌑️🌑️ Starting off easy with some simple calculations

2. 💫️🌑️🌑️🌑️🌑️ Abs + sign to calculate whether or not a report is safe.

3. 💫️🌑️🌑️🌑️🌑️ Look in computer memory instructions string for MUL(x,y) with some regexes

4. 💫️💫️🌑️🌑️🌑️ Finding X-MAS patterns in a grid of characters

5. 💫️💫️🌑️🌑️🌑️ Ordering pages according to a ruleset, basic sorting algorithm

6. 💫️💫️💫️🌑️🌑️ Grid walking until out of bounds + cycle prediction

7. 💫️💫️🌑️🌑️🌑️ Recursion for calculating all possible number equation outcomes using operators (+, \*, ||).

8. 💫️💫️🌑️🌑️🌑️ Finding antinodes in a grid of antennas with different frequencies

9. 💫️💫️💫️💫️🌑️ Filesystem disk / block defragmenter

10. 💫️💫️🌑️🌑️🌑️ Finding all possible routes in a heightmap grid

11. 💫️💫️🌑️🌑️🌑️ Applying rules to a line of rocks, like a growing 1d game of life. ([2021 day 6](https://adventofcode.com/2021/day/6))
