Almost walked away from this when caught out by the "empty" space flipping. But stuck with it and managed to make it work without changing my approach too much.

I enjoyed this one, despite all the reading. Felt like a nice change of gear from yesterday's. Using recursion to read sub-packets from the binary string, using a function that returns the value (or version sum in part 1) as well as the length, so I know where to read from for the next sub-packet.

[2023 Day 5] Exlplanation Like I'm 5
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.

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 :-)
