CryingAngel

My solution for "crying angel" problem.

Installation

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

Usage

require 'crying_angel'

ol = Location.new(0, 10)   # Olenka's location
il = Location.new(301, 10) # Ivanko's location
al = Location.new(0, 0)    # Angel's location

p angel_cries?(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
