Cyrus Innovation code test in Python
See http://www.cyrusinnovation.com/code-test-java/ to learn what that means.
Note that I'm playing around with Python here, and not necessarily writing good (clean, idiomatic) code.
I do have a Java version, but I don't plan to post it publicly, because I believe Cyrus still uses the test. If you need to see it for some reason, let me know!
