Hi there! Thanks for checking out my Advent of Code repo!
I solve Advent of Code problems in Java, making extensive use of its Stream API. I also like to refactor generic concepts into abstractions, to keep the code as easy to read as possible. Though sometimes I still succumb to the chaos monster!
Feel free to use this repo to learn about solution directions, or fork it as a template for your own solutions :)

"Mom: No, we have functional programming at home."
"Functional programming at home: Java Stream API."
(this year I did every day using ridiculous Java streams, enjoy :D)
