Problem Statement

Create a `Cat` class returning ‘Meow’ and a `Dog` class returning ‘Woof’ in a method `speak()`. Create a mixed list containing one Cat, one Dog, and another Cat. Iterate through the list and print their sounds.

Input Format

None

Output Format

Print the three sounds on separate lines.

Constraints

None

Sample Output

Meow
Woof
Meow

Explanation

Because Python utilizes dynamic duck typing, you can iterate through a list of entirely different objects and invoke shared methods smoothly.

Starter Code

class Cat:
    pass

class Dog:
    pass

if __name__ == '__main__':
    # Create list, iterate, and print speak()
    pass
