I completely forgot about the first few days ;( now I’m back and excited to get started this year!

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.

Hello Team. Excited to be here. My First AOC and I'm super excited. Hoping to learn more idiomatic kotlin.

How does the scoring work again? does it penalise you for submitting an answer late? 🤔

Join us for Day 3 of Advent of Code 2022! 💫 It’s starting today at 5:00 PM UTC. There will be opportunities for you to ask questions. See you there!

Not kotlin related but too good to not share: https://www.reddit.com/r/adventofcode/comments/zb98pn/2022_day_3_something_weird_with_copypasting/

TLDR: aoc helped someone discover a virus on their computer

object Day4 : Challenge() {
    val parsed = input.lines().map { line ->
        line.split(",").map {
            it.split("-").map(String::toInt).let { (a, b) -> (a..b).toSet() } }
        }
    override fun part1() =  parsed.count { (a, b) -> a.containsAll(b) || b.containsAll(a) }
    override fun part2() =  parsed.count { (a, b) -> a.intersect(b).isNotEmpty() }
}

Thanks Kotlin for the

..

:)

👋 Can you add another private leaderboard please? They’re all full 🙂

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

📣 Livestreaming Day 4 now! Join us, ask your questions

Is it cool if I post my Twitch streams here when I start AOC problems?

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’d love to have

fun <T> Iterable<Iterable<T>>.transpose()

in stdlib 🙂

Today I had lots of fun messing up the directions

Follow along as we solve an #AdventOfCode Day 5 puzzle in Kotlin. Join us for today’s livestream, sharpen your skills, and ask your questions!

👋 Hallo Team! Day 5 is the day when I found out I'm not good at kotlin xd

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:)

windowed ftw

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

Next up - ?

this year is the first year that I solve questions and seen others that have another solution for a question. that is absolutely amazing to me. I think I'm in a competition and this makes me more energetic to continue...

🔔 In today’s livestream, @antonarhipov will walk us through the problem statement and discuss possible approaches to solving puzzle #6. Join us live at 5:00 PM UTC!

Newborn 👶 naps seem to be getting shorter and shorter 😅, but I’ll keep at it! 🎄

Wanted to do the AOC in 4 languages (Kotlin, Java, Swift and Typescript) A breeze in Kotlin but in Java…😭 when your spoiled with concise languages. https://github.com/bendh/advent-of-code-2022-kotlin https://github.com/bendh/advent-of-code-2022-java

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)?

Nothing like a little recursion to warm up the brain cells!
