Q1. What is polymorphism?
Ans. 
Polymorphism is the ability of a single function or method to operate on different types of data.
• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example: Inheritance in Java allows a subclass to override a method of its superclass, exhibiting polymorphic behavior.
