I have a question in Part 1. Let me show my solution first:

def solve(), do: root()

A little bit late – but it worked on the first try. I have added a little animation – mostly stolen from a solution of José from 2021. Th...

Couldn’t find a thread for this day so sorry if it already exists. I’m stumped. I’ve got a solution that works for the sample data but is...

Today was fun and I got it right the first time :slight_smile: MapSets saves the day again.

Ok, that was a rough one today.
I haven’t found a way to improve the algorithm further. Part 1 runs in .5 seconds, Part 2 in ~ 5 minutes...

I couldn’t find a faster solution in part 2, so I just brute-forced my way. I’m looking forward to smarter solutions.

This one was really fun contrary to other “implement something CPU like” puzzles in the past. I used a bunch of Stream API and a module f...

Took a while, but another use case for “move vectors” today and pattern matching. :slight_smile:

This one has been quite the ride. Struggled at first to find a good data format to suite the problem. I really like how that turned out b...

Today’s challenge is quite interesting. I ended up using Zipper to solve this problem. Maybe I overengineered quite a bit.

Today’s challenge for me was about using reduce:

Probably not the most efficient implementation, because part 1 took >1 ms and part 2 >4ms, but the code was simple enough.

Reasonably pleased with my solution. The bitstring packet problems are so well suited to Erlang/Elixir it’s almost not fair.
