Functional Programming exercises in Scala 3: Functions on Lists

These 22 exercises should be useful to anyone looking to practice in Scala 3 and/or Functional Programming (FP). By and large, they are a curated selection of the “Working with Lists” problems on the OCaml website. The problems are vaguely sorted based on their overall complexity. All solutions provided here are my own so feel free to send me yours if they are any better.
