    Somehow the description for part 2 made it seem to me like it's more complex, where it was in fact simpler than part 1.

    In case anyone else isn't using an input downloader: I've written something up in kotlin/ktor that will a) download the input if it should exist b) throw if you're too early or c) when called just before releases, wait until the clock strikes midnight EST ( + delay), then grabs it. All using suspend fun + coroutines. Will probably add an auto-submitter and checker later. https://github.com/CognitiveGear/AdventOfCode-Kotlin/blob/main/common/src/main/kotlin/Utils.kt

    I started to write a parser for the first part and then, about halfway through, just decided to type it in manually. Cheating? (No more than using AI!) I printed out the whole map and just typed in the top. Part 2 was just to move the last n chars.

    I finished Day 5 on Twitch: https://www.twitch.tv/videos/1671429084?t=00h00m49s. Super open to suggestions as I am very new to Kotlin. This heavily features the konbini parser combinator library (which is :kotlin-intensifies:)

    So I "enhanced" the Day 02 challenge by adding Lizard and Spock to Rock Paper Scissors and had fun playing around with Kotlin features like making a DSL and using property delegation and operator overloading. I absolutely LOVE the expressive power of Kotlin! https://github.com/ty-garside/aoc-2022-in-kotlin/blob/main/src/Day02.kt

    Sort of fun bonus day 6: does your code still work if you move the input to line 2 in the input file (if you use one)?
