what is polymorphism, what is fibbanocci series

Question

Accepted Answer

Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon. Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones.

Polymorphism allows different objects to be treated as instances of a single class, enabling flexibility and reusability in code.
Fibonacci series starts with 0 and 1, with each subsequent number being the sum of the two preceding numbers (0, 1, 1, 2, 3, 5, 8, ...)
Polymorphism example: a shape class with different subclasses like circle, square, triangle, each implementing a method 'calculateArea' differently.
Fibonacci series example: 0, 1, 1, 2, 3, 5, 8, 13, 21, ...
