Welcome!

This is the home for my solutions for Advent of Code challenge using Scala

Approach

I'm using a functional approach for each solution. Which means:

1. avoiding null
2. pure functions
3. immutable values
4. recursion\tail-recursion
5. functional data structures
6. functional control flow (no for-loops, no while-loops)
7. whenever I use if there is always else

Tools

I'm using IntelliJ IDEA running scala worksheets

** Note: in order for a worksheet to execute, you need to enable build before run
