Use Floyd's Tortoise and Hare algorithm to detect loop in a linked list.

• Initialize two pointers, slow and fast, at the head of the linked list.

• Move slow pointer by one step and fast pointer by two steps.

• If they meet at any point, there is a loop in the linked list.

OOP (Object-Oriented Programming) is a programming paradigm based on objects and classes, promoting code reusability and organization.

• Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).

• Inheritance: Mechanism to create a new class using properties and methods of an existing class (e.g., a 'Dog' class inheriting from an 'Animal' class).

• Polymorphism: Ability to present the same interface for different data types (e.g., method overri...read more
