Data structures are ways to organize and store data efficiently.
Data structures are used to store and manipulate data in a structured manner.
They can be classified into linear and non-linear data structures.
Examples of data structures include arrays, linked lists, stacks, queues, trees, and graphs.
Array and linked list are two different data structures used for storing and accessing data.
Array is a collection of elements of the same data type stored in contiguous memory locations.
Linked list is a collection of nodes where each node contains data and a reference to the next node.
Arrays have fixed size, while linked lists can grow or shrink dynamically.
Accessing elements in an array is faster than in a linked list...

Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.
Start from the first element and compare it with the next element
If the next element is smaller, swap them
Repeat this process for all elements in the array
Continue this process until no more swaps are needed

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.
Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.
Inheritance allows code reuse and promotes code organization.
The existing class is called the parent or superclass, and the new class is called the child or subclass.
The child class inherits all the properties and methods of the parent class and can also add new properties and methods.
