This repo contains my Advent Of Code 2021 solutions in C# using .NET 6.0.
This repo is a learning opportunity (a "my first C# project") and thus is likely full of horrors and bad practices.
For a more user-friendly repo, go here: Advent of Code 2021 Solutions.
There are two supported methods for inputting your puzzle data into this application.
First, get your cookie session data.
You will need to log into the Advent of Code website and then inspect your cookies. If you are using Chrome, you can follow the directions here.
You will be looking for a cookie called session. It will contain a long sequence of hexadecimal digits.
Place that data into a file called cookie.txt in the project directory.
The application will use that data to automatically fetch your puzzle input for each day.
This code will also look in a particular location on your local machine for puzzle input.
In the project directory, it will check a directory called puzzle.
Within that directory it will expect Day 1's input to be in a file called 1, Day 2's input to be in a file called 2, etc.
You can find your puzzle input for a given day by logging into the Advent of Code website and then navigating to the URL for that puzzle's input.
The URL for your puzzle input will be at:
https://adventofcode.com/2021/day/${DAY}/input
where ${DAY} is the day number of the puzzle.
As an example, Day 1's input is at https://adventofcode.com/2021/day/1/input, Day 2's input is at https://adventofcode.com/2021/day/2/input, etc.
