Ruby Golf Saigon

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.

Rules

• 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
