Generate a project for a new daily challenge

To generate a project for a new daily challenge, run:

bash scripts/generate_day.sh --day 8

This will produce a day-8 (or day-{num}) directory with the following structure:

day-8/
├── go.mod
├── input.txt
├── main_test.go
├── main.go
├── README.md
└── test.txt

Details:

• The README should contain the challenge prompts
• input.txt should contain the input you are given for the problem, whereas test.txt should contain the example data found within the challenge prompt
• main.go should contain the main logic for solving both part 1 and part 2
• main_test.go should have tests to verify that the solutions work on the provided sample data

Get a solution

To get a soultion for a specific daily challenge, run:

bash scripts/get_solution.sh --day 8 --complex

The --complex flag specifies that you want the solution for part 2. If you omit it, you will get the solution to part 1.

Run tests

You can easily run all the available tests within the daily challenges subdirectories using the command:

make test
