Polymorphism With an Interface

The IAnimal interface declares string Speak(). Complete the Dog and Cat classes so Dog.Speak() returns Woof and Cat.Speak() returns Meow. The tester puts both in a List<IAnimal> and prints each sound on its own line. Do NOT write a Main method.

The program prints the output shown in Expected Output.

Expected Output:

Woof↵
Meow↵

= newline. The output ends with a newline — print one after the last line.
