Object-oriented programming (OOP) is a programming paradigm that organizes data and behavior into reusable objects.
OOP focuses on creating objects that contain both data and methods.
Encapsulation, inheritance, and polymorphism are key principles of OOP.
Encapsulation hides the internal details of an object and provides a public interface.
Inheritance allows objects to inherit properties and methods from parent classes.

Hashmap is a data structure that stores key-value pairs and allows constant time access to values based on their keys.
Hashmap uses a hash function to map keys to indices in an array.
Collisions can occur when multiple keys map to the same index, which can be resolved using techniques like chaining or open addressing.
Examples of hashmap implementations include Java's HashMap class and Python's dict type.

Recursion can be used to solve problems that can be broken down into smaller sub-problems.
Inheritance allows for code reuse and helps in creating a hierarchy of classes.
Heap is used for dynamic memory allocation in la...
