Merge Sort in Data Structures Merge Sort is a popular Divide and Conquer algorithm used to sort arrays or lists efficiently. It works by recursively dividing the array into smaller halves, sorting them, and then merging the sorted halves back together. ⚙️ How Merge Sort Works Divide: Split the array into two halves …

Here, you can find some basic Java example codes to help you get started.

Super and This keywords of Java Super Keyword: Definition: super is a reference to the immediate parent class of the current object. It is mainly used in the context of inheritance. Usage: Call the parent class's constructor: super() can be used to call the constructor of the parent class. This is often used to …

Multithreading in Java is a powerful feature that allows concurrent execution of two or more threads within a program. A thread is a lightweight subprocess and the smallest unit of processing, and multithreading helps improve the performance and efficiency of applications, especially those requiring multiple …

A linked list is a fundamental data structure used in computer science to organize and store a collection of elements. Unlike arrays, linked lists do not require a contiguous block of memory and can efficiently handle dynamic memory allocation. Key Characteristics Nodes: A linked list is composed of nodes, where each …

A stack is a fundamental data structure in computer science that operates on a Last In, First Out (LIFO) principle. This means that the last element added to the stack is the first one to be removed. You can think of a stack like a stack of plates: you add new plates to the top and remove them from the top as well. Key …

A circular queue is a data structure that operates on a First-In, First-Out (FIFO) basis but with a circular arrangement. Unlike a linear queue, where elements are added at the rear and removed from the front, a circular queue connects the last position back to the first, forming a circle. This allows for efficient use …

A simple queue is a fundamental data structure that follows the First-In, First-Out (FIFO) principle. This means that the first element added to the queue will be the first one to be removed, just like people standing in line—whoever gets in first is served first. Key Operations in a Simple Queue: Enqueue (Insertion): …

An array is a data structure used in programming to store a collection of elements, typically of the same type, in a fixed-size sequence. Initialisation of Array 1#include <stdio.h> 2int main() 3{ 4 // it's not important to give size during initialisation. 5 // eg: float y[]={1.2,2,3.32}; 6 7 int g[5]; 8 int …

C is a powerful, general-purpose programming language that provides control over system resources and efficient execution. This post will cover some essential concepts in C that every programmer should understand: Control Strings, Global Variables, Strings, Switch Statements, Ternary Operators, Unformatted …
