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
A program to print all prime numbers
Take input from user for range of numbers
Loop through the range and check if each number is prime
Print the prime numbers
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.

A stack is a data structure that follows the Last In First Out (LIFO) principle.
Elements are added and removed from the top of the stack.
Common operations include push (add element) and pop (remove element).
Stacks are used in programming for function calls, expression evaluation, and more.
DOM stands for Document Object Model. It is a programming interface for web documents.
DOM is a tree-like structure that represents the HTML or XML document.
It allows developers to manipulate the content and structure of a web page using scripting languages like JavaScript.
DOM provides a way to access and modify the elements, attributes, and text content of a web page.
It also allows developers to add or remove elements ...
An interface is a contract between two components that defines the communication between them.
An interface defines a set of methods that a class must implement.
Interfaces allow for polymorphism and loose coupling.
Interfaces can be used to define common behavior for unrelated classes.
Examples include the Java Collection interface and the USB interface.
Insertion sort is a simple sorting algorithm that iterates through an array and places each element in its correct position. Merge sort is a divide and conquer algorithm that divides an array into two halves, sorts them separately, and then merges them back together.
Insertion sort has a time complexity of O(n^2) while merge sort has a time complexity of O(n log n)
Insertion sort is efficient for small data sets while me...
