Morning All. Here are some rather easy problems for you to solve. The rules are simple. Keep it functional. No mutable state, no for loops. That sort of thing. And it is in Scala, you may need to learn this in a hurry.
Get going by cloning this repo and installing the Scala Build Tool
on whatever passes for your compute facility. Run the test cases using sbt test. It may take
a few minutes to download all the libraries and the compiler. Have coffee. If you want to
see why some of us like Scala, use sbt ~test and watch the retest as you edit.
Thanks to S-99 and Josh Sureth for the problems, solutions and inspiration.
