Encapsulation, Inheritance, Polymorphism, Abstraction

• Encapsulation: Bundling data and methods that operate on the data into a single unit (class)

• Inheritance: Ability of a class to inherit properties and behavior from another class

• Polymorphism: Ability to present the same interface for different data types

• Abstraction: Hiding the complex implementation details and showing only the necessary features

A linked list is a data structure where each element points to the next element. Reversing a linked list involves changing the direction of pointers.

• Linked list: A data structure where each element (node) contains data and a reference to the next node.

• Reverse a linked list: Iterate through the list, changing the direction of pointers to point in the opposite direction.

• Example: Original list: 1 -> 2 -> 3 -> 4. Reversed list: 4 -> 3 -> 2 -> 1.
