Solutions to a few of the Advent of Code (AoC) 2021 puzzles in Kotlin.
Why just "a few"? I'm actually primarily working in Ruby for my AoC 2021 solutions! However, I was intrigued by a sponsored message that JetBrain was running on the Advent of Code site:
Get ready to jingle with Advent of Code in Kotlin! Have fun, learn new things, and win prizes. Believe in magic with Kotlin. Happy holidays! https://jb.gg/AoC
That link redirected to a post on the JetBrains / Kotlin blog inviting developers to try out the Kotlin language via the AoC problems, and providing a nice Kotlin AoC GitHub template as a starting point.
I'd never worked with Kotlin before, but I have used AoC to try out new programming languages before. Serendipitously, I had some time available on the same day in which I came across the ad, and so I decided to give it a go!
(So, Kotlin team, if you're reading this: The combination of your ad on the AoC site, your blog post, and your GitHub template worked! Nice going! I almost never click on ads!)
