This year I decided to solve the Advent of Code puzzles using F#, the functional programming language for .NET. Since I had very little previous experience with F#, this meant a lot of learning about the language as I was implementing my solutions. For one of the puzzles, memoization seemed the best approach, which meant I had to find a way to implement it in F#.
It's December again and for the third year in a row I've spent a significant amount of time solving Advent of Code programming challenges. To make it even more interesting, I decided to write the solutions in Kotlin - a programming language I heard a lot of good things about, but had no prior experience in.
For the second year in a row, I spent a significant amount of time in December solving the Advent of Code programming puzzles. Before writing the first line of code, I created a repository for my solutions. Unlike last year, I wanted to have all the code readily available for future reference. More than once, I actually looked up previous solutions while solving a more recent puzzle.
