# AdventOfCode2020

My (attempted) solutions to [Advent of Code 2020](https://adventofcode.com/2020) in Elixir.

## Strategy

If this year is like 2018, the last time I did this, each problem will be split into multiple parts.
Later parts can result in considerable refactoring of earlier parts, so I will split each part into its own file, like this:

* `day1/`
  * `day1.exs` (when the solution is only in one part)
* `day2/`
  * `day2part1.exs`
  * `day2part2.exs`

If I get stuck, my instinct is to be persistent and take as long as it takes to solve the problem.
However I think this year I don't want the pressure of days piling up and this is supposed to be fun,
so I will probably limit each problem to one day, and then come back to those that I had problems with later.

**No checking other people's solutions** until I've solved it myself - or otherwise given up.
I will not check in code that was written as a result of seeing other people's solutions or reading forums, etc.
