To start coding on this challenge, first install all gems:
bundle install
Then, execute the test using guard:
bundle exec guard
Each time you change ruby_golf.rb, the tests are re-run and give you the state of your implementation and code metrics used for ranking.
- only touch
ruby_golf.rb - implement your solution within the pre-defined module methods
- only non-whitespace characters within the method body are counted, no need to optimize the method definition
- you can implement helper methods within the module, but be aware that they are counted towards the size of each method they're used in
- stick to what stdlib gives you
- DON'T use custom gems
- DON'T go and annoy the organizers by being clever and exploiting their code
