To practice:
solve any of the suggested problems on recent lecture,
or any of those suggested at the bottom of a recent lab.
(The lab problems, if you include main
interactively reading
from a Scanner,
will use 2-3 functions total.
Think about how to break the problem down into a helper functions.)
You will be provided with the summary documentation for any built-in Java methods
you might need
(String, java.util.Scanner, java.util.Random).
