Sealed Override

The base class Widget has a virtual method Draw. In the Button class, provide a sealed override of Draw that prints Draw button. The sealed keyword lets you override the method here while preventing any further subclass from overriding it again. Do NOT write a Main method.

The tester runs Widget w = new Button(); w.Draw(); and the program prints the output shown in Expected Output.

Expected Output:

Draw button↵

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