# Here are a few very simple tests to run on your functions to ensure that they
# have the signatures that we specified. (A signature of a function is the
# type and order of the parameters and also the type of the returned value.)
#
# These basic tests do NOT thoroughly test your code. Do that yourself.
# They provide a confirmation that your understanding of the types of each
# parameter was correct. If one of your functions does not pass one of these 
# tests or does not even complete, then something is wrong and you should 
# come to office hours before submitting your solution.
#
# Only the first two tests specify the output. For the next five, you'll need
# to read the input and work out the output that you should be expecting.
