I'm planning on using 10 languages to retrospectively solve all the previous years' questions:

1. Python
2. Rust
3. Go
4. Typescript
5. Kotlin
6. Lua
7. Elixir
8. Haskell
9. Zig
10. Ruby

I use a different language every year, as a way of learning that language. So far I've used Elixir, Typescript, Rust, and Clojure.

I typically use Python and PowerShell, mainly as a shameless excuse to write more Python and PowerShell
