+- Writing the input parsing code takes a whole bunch of time. I should do something about that.
+- I should look for duplicated logic and refactor code to leverage some utility code. E.g. wrap-around slice/vector might be useful for a bunch of puzzles.
+- I still feel I'm sometimes fighting the borrow checker. I need to work on my Rust skills, and perhaps
+do some things differently.
