My code in Python3 here.

Here is my repo : https://github.com/lehippie/advent-of-code

So, I developed a Python class to manage input parsing and solve day parts. With it, I only have to call the solve() method and he current status or the puzzle is printed to stdout. This helps to avoid regressions when tinkering in part_two with an already solved part_one.

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.

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 :-)
