I am using C# for this year's challenge. I'd consider myself proficient in C#, but on a day to day basis I don't use it as much and would just like to get more practice with it.

Structure

Each day's solution is contained in a separate folder. Each folder contains:

A PROBLEM.md file containing the problem description.
A INPUT.txt file containing the input for the problem.
A dotnet console application containing the solution.
An xUnit test project containing unit tests for the solution.

Prerequisites

.NET 8.0

Running the Solutions

To run the solutions, navigate to the solution folder and run the following command:

dotnet run -- <path-to-input-file>

Or for part 2 solutions

dotnet run -- <path-to-input-file> part2

Challenges

Day	Problem	Solution	Status	Notes
01	Problem	Solution	✅	The trickiest part here was accounting for overlapping digit words.
02	Problem	Solution	✅	The key to me here was to parse the input into a useful model.
03	Problem	Solution	✅	The edge case that got me here was lines ending with a part number.
04	Problem	Solution	✅	Part 2 gets out of hand quickly with just 200 cards.
