Day 1 Notes
------
Part1:
------
$ elixir day1part1.exs
618 x 1402 = 866436
Thoughts:
Avoid iterating seen elements by consuming the list, and comparing each list element only to the remaining
elements.
------
Part2:
------
$ elixir day1part2.exs
547 x 545 x 928 = 276650720
Thoughts:
Use a comprehension over two versions of the remaining list to efficiently compare the three items.
