Repository for my solutions to the Advent of Code programming challenges.
There is a test in Helpers.cs which sets up each day and grabs your unique input for you.
As we are not supposed to share inputs, these are stored in a different folder. The path to this folder is stored in an environment variable named ADVENT_OF_CODE_INPUT_PATH.
There is another environment variable named ADVENT_OF_CODE_SESSION_KEY. If this contains the value of your session cookie (when logged in) on the Advent of Code website then the helper code can grab inputs for you.
Each days solution goes in a class that inherits from AdventOfCodeBase<T>. This abstract base class configures all of the tests for you and provides virtual methods for Solution1 and Solution2. Override these and return the result. The infrastructure will run every input over them and store the result in a .received.txt file named after the input and the part of the problem (one or two). It will then compare this to a .approved.txt file with the same prefix. If they are the same the test passes.
Solve the problem. When you have the right result, copy the contents of the .received.txt file into the .approved.txt file. Now, subsequent runs will pass.
