Advent of Code

Advent of code: https://adventofcode.com/

Each day from first to 25th of December has a new problem to solve, with an additional part 2 problem as a bonus. Every problem has example data, but the problem should be solved with a personal set of data. The output will typically be a number or a sequence of numbers/characters.

Run scripts

The two scripts in this project creates a new solver for the new task and runs the task solver with the proper input.

create a new solver from boilerplate

This script will create a folder and a solver with template code for the given year and date.

$ yarn init-solver 2022 1
> https://adventofcode.com/2022/day/9
> ✨ Done in 1.19s.

run the solver with personal puzzle input

The script will use your session cookie and fetch your personal input data for the given year and day.

Run in a terminal yarn solve [year] [day] or add a + sign in the end for part two.

$ yarn solve 2022 1
> The answer is 7746

$ yarn solve 2022 1+
> The answer is 2604

Cred

Was inspired by @atme's advent-of-code repo for fetching the input data.
