## How to Reverse a String in C?

One major challenge that is well-known in many problem banks for competitive coding is reversing a string. First, let's define a string. A string may alternatively be defined as an...

## CPP Program to Find the Frequency of Elements in An Array

For each unique element in the array, we must count its occurrence in this program. Maintaining one array to hold the counts of each array element is one strategy for...

## Representation of Stack using Array

Stack is a linear data structure that executes all operations according to the LIFO (Last In First Out) principle. Only one end of the stack, starting from the top, is...

## Program to Find GCD of Two Numbers in C++

The highest common number that divides two integers without leaving a remainder is known as the GCD (Greatest Common Divisor). Highest Common Factor, or HCF, is another name for GCD....

## C++ Program to Find the LCM of Two Numbers

The lowest number which is a multiple of all the supplied numbers is known as the Least Common Multiple or LCM, of a collection of integers in mathematics. In C++,...

## CPP Program To Check Whether A Year Is A Leap Year Or Not

Every four years, an extra day is added to the year i.e., February 29, to synchronize the calendar year with the solar year. That year is known to be the...

## Expression Tree in Data Structure

A data structure called an expression tree is used to describe expressions that take the shape of trees. After creating an expression's expression tree, we may execute inorder traversal to...

## Red Black Tree in Data Structure

Red Black Tree is a type of balanced Binary Search Tree that uses a unique set of principles to ensure that the tree remains balanced at all times. Let us...

## Which Data Structure is used for Implementing Recursion?

Stack(LIFO) data structure is one of the famous data structures used for implementing recursion. Recursion is a method of problem-solving where a function is run repeatedly on smaller inputs until...

## CPP Program to Check whether a Number is Palindrome or Not

A palindrome is a unique number that is exactly the same as from the forward and backward. We notice palindromes everywhere in daily life, from the numbers on a date...

## CPP Program to Print Fibonacci Series up to N Numbers

The Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones, usually starting with 0 and 1. This series is an important...

## How To Run Python Program?

Python, with its simple syntax, versatility, and vast ecosystem of libraries, has become one of the most popular programming languages for a wide range of applications, from web development and...

## ArrayList Program in Java

In Java programming, ArrayList is a widely used data structure that provides dynamic array-like functionality. It belongs to the Java Collections Framework and allows for the creation of resizable arrays,...

## Difference Between Linear and Non Linear Data Structure

Data structures serve as the foundational elements of computer programs, tasked with the storage, organization, and manipulation of data. They fall into two main categories: linear and non-linear structures. Linear...

## Sparse Matrix in Data Structure

A sparse matrix in data structure is an important concept in data structures and algorithms, providing an efficient way to store and process large matrices Sparse matrices are widely used...

## Primitive Data Structure

Primitive data structures are the most basic type of data structure. They are built into most programming languages and provide a simple way to store data in its raw form....

## Linear Data Structure

Data structures play a crucial role in solving complex problems. They are used to organize and store data in a way that allows efficient access, modification, and retrieval of the...

## Hash Function in Data Structure

A hash function, in its simplest form, converts a significant number or text into a tiny integer that may be used as the index in the hash table. The pair...

## Graph Traversal in Data Structure

A graph is a non-linear data structure composed of vertices and edges. Edges are lines or arcs that connect any two nodes in the network. Vertices are also known as...

## Graph Representation in Data Structure

A graph is a type of data structure that represents a collection of objects called vertices or nodes that are connected by an edge network. A graph's nodes typically represent...
