Here are my solutions for Advent of Code 2021.

This year, I decided to learn (and use!) some Kotlin. Hopefully it goes better than Rust last year :P.

I've been running .kts files via:

kotlinc -script main.kts < /tmp/input.txt

And running .kt files via:

kotlinc main.kt -include-run -d /tmp/main.jar

java -jar /tmp/main.jar < /tmp/input.txt

Enjoy!
