# Advent of Code 2023
## About
This repository stores my solutions to the daily challenges of [Advent of Code Calendar 2023](https://adventofcode.com/2023/).
## Execution
Any of the scripts can be executed directly using [NodeJS](https://nodejs.org/en/download/).
**Example:**
```bash
cd Day01/
node Part1.js
```
## File explanation
A single challenge consists of 3 files:
- `input.txt`: My input data, as provided by AoC.
- `Part1.js`: My solution to part 1 of the challenge.
- `Part2.js`: My solution to part 2 of the challenge.
Other special files:
- [`template.js`](template.js): A template file to use when initializing a new challenge.
- `sample.js`: Example or test code; Ignored by git (see [.gitignore](.gitignore)).
