After that, it was a fairly simple loop, nothing too complicated. The full code is here, and the generated raw brainf*ck is alongside it: 975 lines of nonsense. And that's it! My last brainf*ck solution of the year; i didn't expect to be able to solve that many days: 1, 2, 4, 6, 9, 10, and now 25... I've learned a lot, expended my library of macros quite significantly, and now i know what to clean for next year!

I don't have such functions: i have time-travelling hash-maps. :P

part 1, original, transpiled

For part 2, i used the transpiler. I duplicate the buffer of 14 cells, sort it using a bubble sort, and then only do 13 comparisons.

As usual, code on Github, recording on Twitch.

Code on GitHub is currently a mess.

In the spirit of the Day 5 ALLEZ CUISINE! challenge to ELI5 (Explain Like I'm Five), here's a tasty explanation of how my algorithm works using only a large bucket of Red Vines and a knife. It says to use lined paper, but if you try this at home consider aligning things on a cutting board.

Elixir code, thoughts

Elixir 1554/1502 code, reflections

Elixir 2506/3402 (24 minutes, 2 hours), code, thoughts

Bonus solution in Go (golang) because I was confused about why my Elixir solution didn't work and decided to implement from scratch in case I'd done something dumb. The Go one also got the wrong answer, but took less than 100ms instead of a minute, so I could try out lots of tweaks that didn't change the answer.

Elixir 2031/2641 after 3.25/6.5 hours! Code on GitHub

I spent time this afternoon sprucing up my helpers for the iex REPL. I spent a bunch of time poking at things in IEx the last couple days and wanted to make sure I would minimize keystrokes if I needed to debug things on my phone while drunk. Turns out Thursday night > Friday night > Saturday night in terms of difficulty, so all those macros have so far saved me zero seconds :-)
