My solution for "crying angel" problem.
Clone a repository and execute the following sequence of commands:
bundle install bundle exec rspec gem build crying_angel.gemspec gem install cyring_angel-0.0.1.gem
require 'crying_angel' ol = .(0, 10) # Olenka's location il = .(301, 10) # Ivanko's location al = .(0, 0) # Angel's location p (ol, il, al) # => true
Go to specs to find more examples. Here is how it looks with formatted documentation option:
#angel_cries? angel can not see Olenka but can see Ivanko returns false angel can not see Ivanko but can see Olenka returns false angel can not see both returns false angel can see both returns false if distance between Ivanko and Olenka <= 300 km returns true if distance between Ivanko and Olenka > 300 km
