Advent of Code

I return to Advent of Code for its gradual progression of challenges and the community that forms around solving them. The exercises provide a recurring reason to explore algorithms, data structures and unfamiliar problem shapes.

Kotlin is particularly enjoyable in this setting. It can feel like a bridge between Java’s practical ecosystem and some of the expressive qualities I value in Haskell.

The toolkit between the answers

Individual solutions are only part of the collection. Over several years, the repository has accumulated reusable support for:

• loading inputs and running puzzles
• parsing and transformation
• two-dimensional grids
• combinatorial operations
• dynamic-programming patterns
• shared utilities used across different years

That evolving toolkit is the more meaningful artifact: a record of how repeated problem-solving gradually produces a personal working environment.

The collection remains ongoing whenever I participate rather than representing one completed season.
