🎄 🎁 Advent of Code 2024 🎁 🎄

Advent of Code is an annual event that runs during the first 25 days of December. Each day, a new programming puzzle is released on the Advent of Code website. The puzzles typically involve problems related to algorithms, data structures, and computational thinking.

This repository contains my solutions to the Advent of Code 2024 challenges, written in Go. I'll be updating this repo daily with new solutions as the puzzles are released.

AOC cli Tool

Additionally, this repo includes a CLI tool that can be used to easily fetch each day's input.

Flags:

• -n (int, required): Day number (1-25)
• -y (int, optional): Year (default 2024)
• -o (string, optional): Output filename (default 'input.txt')
• --dir (string, optional): Output directory (default: day01 - day25, based on -n flag)

Examples/Usage:

The SESSION_COOKIE environment variable must be set, either in the shell or in a .env file.

• Day 1 default

aoc -n 1

day01/input.txt

• Day 1 of 2023 with custom filename, output to current working directory

aoc -n 1 -y 2023 -o file.txt --dir .

file.txt
