Introduction

This repository is an attempt to better learn functional C# and do the Advent of Code problems at the same time.

What is functional to me?

I set the following rules for myself, mostly taken from the book Functional Programming with C# and with some personal additions:

1. Don't use if, for, while, etc. Ternary operator ? is allowed
2. Try to use readonly data structures and records as much as possible
3. LINQ is considered functional, so any use of LINQ is allowed
