Sealed Method Override

Base has a virtual method Info returning "base". Create Middle that inherits from Base and provides a sealed override of Info returning "middle", which stops any further class from overriding it. Then create Leaf that inherits from Middle and adds nothing. Do NOT write a Main method.

For a Leaf the program prints the output shown in Expected Output.

Expected Output:

middle↵

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