Advent of Code 2021 in a different language every day

I completed Advent of Code 2021 using a different language for every day. I did have to give up on a couple days and hack out solutions in python to stay current with the group I was competing with, but it only took me a little work to come back later and fix those days up appropriately.

Tracking for days I have to redo in a language I haven't used yet

Results

By day:

Day	Lang
day01	cl
day02	ocaml
day03	prolog
day04	fortran	This is the one I'm choosing to "count"
day04	py	This one works, but I went back later to redo it in fortran.
day05	zig
day06	asm
day07	julia
day08	py	Another functional solution that I had to go back and redo.
day08	swift
day09	d
day10	haskell
day11	nim
day12	typescript
day13	octave
day14	perl
day15	sql
day16	rust
day17	clojure
day18	lua
day19	elixir	Went back and redid it in elixir
day19	py	My initial solution
day19	z3-bad	Nonfunctional
day20	r
day21	cpp
day22	ruby
day23	py
day24	sorta_rust	I ended up doing this one by hand; none of the code participates.
day25	c

By solution:

Lang	Day
asm	day06
c	day25
