Introduce yourself briefly and highlight your skills and experience
OOP stands for Object-Oriented Programming and its pillars are encapsulation, inheritance, and polymorphism
Inheritance is a mechanism in OOP where a new class is created by inheriting properties and methods of an existing class. Types of inheritance are single, multiple, multilevel, and hierarchical
Operator overloading is a feature in OOP where an operator can be given multiple meanings. Overloading of ! operator is used to negate a boolean value
Linked List is a data structure in which elements are linked using pointers. It consists of nodes that contain data and a pointer to the next node
To detect a loop in a Linked List, we can use Floyd's cycle-finding algorithm. We use two pointers, one moving at twice the speed of the other. If they meet, there is a loop. To find the node where the loop starts, we move one pointer to the head and keep the other at the meeting point. Then we move both pointers at the same speed until they meet again. The meeting point is the start of the loop
