You have the following class definitions.
There might be other classes derived from Shape.
You are creating an application that evaluates whether an object is a square, a rectangle, or another shape.
You need to implement a switch statement that meets the following requirements:
• If the shape variable is of the Rectangle type, and the width and the height are NOT equal, the output must be Rectangle.
• If the shape variable is of the Rectangle type, and the width and the height are equal, the output must be Square.
• If the shape variable is of any other Shape derived type, the output must be Unknown.
• If the shape variable does NOT refer to an object, the output must be Empty.
