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.

Setup

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
