Advent of Code 2019
These are my solutions to Advent of Code 2019.
Getting Started
Run every day with yarn start.
Run a single day with yarn start --day <day>.
Example
$ yarn --silent start --day 1
Running day 1
Part 1: 3266288
Part 2: 4896582
Development
src/index.ts is the runner, which needs to be invoked by ts-node since it's
in TypeScript.
Each day is in it's own directory (e.g. src/1/) that contains input.txt, the
puzzle input, and index.ts, the TS module. The TS module must export the
functions part1 and part2, which should return the solutions of each part.
Each solution function starts by calling getInput, a helper function that
reads the local puzzle input and returns an array of lines.
Start a new day
Generate the skeleton code for a new day with npx hygen day new.
