Advanced Scala Playground

Code written while playing with the concepts covered in Advanced Scala Course offered on https://rockthejvm.com/p/advanced-scala.

Note on structure

The main topics covered are residing in lectures and exercises folders in AdvancedScalaDoodle/src/main/scala/. Both lectures and notes contain my comments and testing out various concepts in Scala language. The exercises contain full problem specification and my solution offered.
