This challenge is a little bit different in that no code is provided.
However, you can pull code from previous assignments and/or the course notes (for example, you'll likely want
the Java interface DynamicList.java).
You can also use your previous code and/or answer keys provided on our D2L page.
Here are runnable test cases to help you get started testing your objects -- you can add more tests, but do not modify the tests (they should be run as-is)
