Advent of Code 2024

Advent of Code is an annual series of programming challenges released daily during December. Each challenge consists of two parts, testing problem-solving skills and coding proficiency in various programming languages. It's a great way to practice, learn, and compete with others around the world.

This repository provides Node.js solutions to the challenges for Advent of Code 2024.

Installation of Packages

Run the following command to install the required dependencies:

yarn

Setting Up the Repository

Copy the .env.example file to create your .env file:

cp .env.example .env

Important Note

Ensure you retrieve your session cookie from the Advent of Code website and paste it into the .env file. This will make it easier to fetch and manage daily challenge inputs.

Fetching Days

Use the following command to fetch the input for a specific day:

yarn fetch:day <dayNumber>

How It Works

• The script fetches the input for the specified day from the Advent of Code website.
• It saves the input in the inputs/ directory as day-<dayNumber>.txt.
• If a corresponding script file does not already exist in the src/ directory, it creates a new file named day-<dayNumber>-challenge.js with boilerplate code to read and log the input.
• If a challenge file already exists, only the input is fetched and saved.

Running Challenges

Use the following command to run a specific challenge:

node src/challenges/challenge-name.js
