First, fork the repository on Github, then clone your fork on your local machine:
git clone git@github.com:<github-handle>/puzzles.git
You should create a branch to solve a puzzle:
git checkout -b <github-handle>_<puzzle-name>
When you're ready to start, erase the TODO comment in the puzzle method
and make a commit saying 'Started working on <puzzle-name>.', like this:
git commit -am 'Started working on my_turn_in.'
You can now start coding! To validate your solution, you can run the
tests for an individual puzzle using the test suite. To test the Snake
my_turn_in puzzle, for example, run:
ruby ./test/puzzles/snake/my_turn_in_test.rb
Once you've finished solving a puzzle, you can push your solution to your repository like this:
git push origin <branch-name>
Puzzles can be found in the files contained in the lib/puzzles
directory.
