Advent of Code - Day 5

I’ve been astonished at the speed of some of José’s solutions. I don’t think any of mine are ridiculously slow but comparatively they are.

Solving the problems is one element of the challenge. Making the code faster is another. Making it faster and still understandable is where I struggle the most as an Elixir newbie.

My plan is to re-do the challenges in January to see how my code has evolved over the challenge which is not a long period of time but I’m writing a lot of code and learning new things every day.
