Polymorphic Method Parameter

The Speaker class has a method Announce(Animal a). Because the parameter type is the base class Animal, the same method works for ANY subclass, and a.Sound() runs the subclass's version. Complete Announce so it returns Animal says:  followed by a.Sound(). Do NOT write a Main method.

For a Cow (whose Sound() returns Moo) the program prints:
Animal says: Moo

Expected Output:

Animal says: Moo
