 Note that **you don't need to execute the functions yourself**, the tests are responsible for doing that. All you should do is declare them, make sure they deal with the parameters passed and that they return what is indicated on the iterations and in the test messages. For some iterations we provide you with a sample array, so that you can do some **manual** testing, if you wish.
