Programming Question #1 - Warmup

This is a simple evaluation problem. You'll code Bob, a simple message responder as follows:

  • Bob answers 'Sure.' if you ask him a question.
  • He answers 'Woah, chill out!' if you yell at him (ALL CAPS).
  • He says 'Fine. Be that way!' if you address him without actually saying anything.
  • He answers 'Whatever.' to anything else.

For help in completing the initial problem, specs are attached in each of the following languages: Ruby, Python, JavaScript and Clojure. Please select one language, complete the code in your language of choice so that all specs pass and upload the result to a private Gist here on GitHub. Please send us the URL when you're finished. Thanks!

Note, if you've seen this problem before (we didn't create it!) please submit your solution anyways.
