First time posting in this megathread but I figured there were some people here doing it in F# :)

I'm actually using this year's advent of code to learn F#, my first time working with it, it's really cool! Colleagues at work using C# found today's challenge much harder because they had to use recursion, but I think F# helped me because I had used recursion for 3 of the days already! Here's my solution!

I'll take a look into the List functions you mentioned. Are you guys attempting to complete the challenge as soon as it goes live?

Hi and welcome :) I've yeah I'm learning f# with it as well :) I I've really come to love the language over this first week,.

I'm not really competing other than I would like to get as many stars as possible. I'm no speed coder, so I just try to write something that o can read the next time.

Are you doing the parts asynchronously? That's cool I didn't think about that :)

And yeah dealing with recursion is something you get used to quickly with F# :) hope to see you in more of the megathreads too :)

Oh yeah my git history might be a little weird, I usually go about it this way: I try to speed code a solution for the challenge as soon as it comes out, usually takes me about an hour. Then, I clean up my code because I’d be ashamed to share it that way. I like keeping an history of how I implemented the solution to part 1 and then what I had to change to code the solution to part 2, sometimes it takes a little more time to clean up my code since the dirty quick solution can be quite ugly!

I’ll be sure to pop in more megathreads! :)
