Problem B

Create a class named 'Fish' with a method to print "This is a fish".

Then, create two other classes named 'Jawed_Fish', 'Jawless_Fish' inheriting the Fish class, both having a method to print "This is Jawed Fish" and "This is jawless fish", respectively.

Create a subclass 'Shark' of 'Jawed_Fish' having a method to print "Shark is a jawed fish".

Now call the method of 'Fish' and 'Jawed_Fish' class by the object of 'Shark' class.
