99 Scala Problems Index

I decided to learn Scala. I looked for some good exercises for Scala programmers and found S-99: Ninety-Nine Scala Problems, and since writing about things helps me learning them I am going to write a post for each problem I manage to solve.

The official site provides solutions for the problems, so my solutions will obviously be influenced by those, when not the same.

CAVEAT: I am a beginner so what I state in the following posts may be inaccurate and sometimes wrong. Please submit an issue on the blog GitHub issues page.

This is the index of the problems I already discussed. I kept the original title and difficulty ranking (asterisks)
