Structure

Every solution is grouped by its year and day and (usually) consists of five files:

Filename	Purpose
`<year>/<day>/index.ts`	Has the solution. Exports two functions: `solveFirst(string): number` and `solveSecond(string): number`
`<year>/<day>/index.test.ts`	Unit test using the example input and expected solution.
`<year>/<day>/run.ts`	Basic run script: Loading the actual input and passing it into the two solve functions.
`<year>/<day>/input.txt`	Input text from AOC.
`<year>/<day>/<year>-<day>.run.xml`	IntelliJ/Webstorm runfile for `run.ts` using Bun.

To install dependencies:

bun install

To test all days:

bun run test

To create a new day-folder:

bun run copy.ts

To run a single day, first copy your input file from https://adventofcode.com/<year>/day/<day>/input into <year>/<day>/input.txt. Then run:

bun run <year>/<day>/run.ts
