Advent of Code 2024

This repository contains my solutions for the Advent of Code 2024 challenges.

Languages

I am using C# for this year's challenge again.

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 TUnit test project containing unit tests for the solution.

Prequesties

• .NET 9.0

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

You can also build the projects and run the executables directly.

dotnet build
./bin/Debug/net9.0/<project-name> <path-to-input-file>

Challenges

Day	Problem	Solution	Notes
01	Problem	Solution	A great way to start!
02	Problem	Solution	Damn their was an edge case that really bit me...direction change after first pair of levels
03	Problem	Solution	Thank goodness this wasn't a repeat of day 2.
04	Problem	Solution	This was fun! Definitely was able to see the growth in my abilities here.
05	Problem	Solution	A graph to the rescue!
06	Problem	Solution	I kind of brute forced part two...
07	Problem	Solution	Not perfect or pretty, but good enough
08	Problem	Solution	Without some help from chat I don't know where I'd be...to be fair the description kind of mislead me.
09	Problem	Solution	Doing things with indexes is error prone.
10	Problem	Solution	I recognized the solution for this based on pattern from last year. Solved using BFS.
11	Problem	Solution	Dictionary > List
12	Problem	Solution	CORNERS == SIDES
13	Problem	Solution	Yay for algebra
14	PROBLEM	Solution	Part 2 is not as complicated as you think. The answer is using the safety factor
