Advent of code 2021

The problems are solved in functional-style Python. That is, Python pretending to be Haskell :-) They are also solved in Scala 3.

All code can be run like this:

cat input.txt | ./01.py

or

cat input.txt | ./01.scala

I won't use anything outside of the standard libraries for either language.

Notes

• The Scala Day 04 solution is better: more direct, shorter.
