 Solutions for  Advent of Code (http://adventofcode.com/) in Elixir (http://elixir-lang.org/)
 
 I never used elixir before so pretty much learning both the syntax and functional programming as I go.
+
+Afterword
+----------
+Finished all the problems, lots of brute force and not a lot of thinking/algos
+but the point for me was to try elixir and get a bit into functional programming.
+
+It's a nice set of problems and very well presented so I might try to solve them again in a different
+language or maybe revisit the elixir solutions once I'm more familiar with it.
