The term "perform right rotation on a matrix" refers to shifting each column in the matrix to the right. This operation is repeated "k" times when specified. In other words, it's a right shift of the matrix that occurs "k" times. This program can be implemented using various programming languages but a simple yet effective approach is to consider JavaScript for rotating the matrix right by k times. How to rotate the matrix right by K times? It is straightforward to carry out a right rotation on a matrix by k times, which involves shifting each column of the matrix ... Read More

There are many problems that require a certain level of expertise and creativity to solve. One such problem is determining the minimum number of moves required to make all strings equal. In this article, we will explore how to solve this problem using JavaScript programming. First, let's define the problem. Problem Statement Given an array of strings, we need to find the minimum number of moves required to make all strings equal. In a move, we can move the first character of a string to the end of the same string. Example Consider the following array of strings ["abcd", "cdab", ... Read More

In this tutorial, we will learn about the JavaScript Program for merging two sorted linked lists such that the merged list is in reverse order. We will first understand the problem statement with some examples. Then we will go through a step-by-step approach to solve this problem, including creating a function that takes in two linked lists as arguments and returns the merged list in reverse order. We will also discuss different approaches and their time complexity to help you choose the most efficient solution. So, let's get started and learn how to write a JavaScript program to merge two ...

Given an array of numbers and a range, the goal is to calculate the mean of all the numbers within that range. This problem can be approached in various ways, but in this tutorial, we will explore a simple and efficient solution using JavaScript. We will begin by defining the problem in more detail, including examples that illustrate how the function should work. Then, we will break down the solution step by step, providing clear explanations and code snippets along the way. By the end of this tutorial, you will have a solid understanding of how to write a JavaScript ... Read More

Dealing with time is one of the most common concepts of web developers. Whether to schedule time for the subscription period or schedule email sending requires developers to deal with the time. In this article, we will learn how to design a digital clock using JavaScript. Get The Time On Clicking The Button We can achieve the same operation using multiple logic and codes. First, in this section, we shall learn how to design a digital clock that shows the time when the user clicks on the button. Follow the steps to achieve the step − First, create a ... Read More

Anticlockwise rotation of an array means rotating all the elements of the given array to their left side by the given number of indexes. In this article, we will implement a JavaScript program for range sum queries for anticlockwise rotations of the array by k indices. Introduction to Problem In this problem, we are given an array that will contain some integers and another array that will contain the values in the pairwise form. Each pair will be the number of rotations we need for the current query and after a given number of rotations, we will be given a ... Read More

LCM stands for the lowest common multiple and the LCM of a set of numbers is the lowest number among all the numbers which are divisible by all the numbers present in the given set. We will see the complete code with an explanation for the given problem. In this article, we will implement the JavaScript program for a range of LCM queries. Introduction to Problem In this problem, we are given an array that will contain integers and another array queries that will contain pairwise numbers representing the range from the given array we have to calculate the LCM ...

The Singly-linked list is a linear data structure that consists of nodes. Each node contains the data and the pointer to the next node which contains the memory address of the next node because the memory assigned to each node is not continuous. Sorting is a technique by which we make all the elements of a particular data structure such as a linked list, array, vector, etc in a properly sorted manner in either increasing or decreasing order (if not specified in increasing order). We will see the proper code and the explanation in this article. Introduction to Problem ... Read More

Rotating array means we will be given a number and we have to move the elements of the array in cyclic order in either the right or left direction. Here we are not specified so we will use the right rotation as the standard and after the given number of rotations, we will return the subarrays with the maximum sum. We will see the code with the proper explanation in the article. Introduction to Problem In this problem, we are given an array that contains the integers and another array that contains the pairs of queries. Each index of the ... Read More

Rotation of the given string means moving the characters of the given string in clockwise or anticlockwise manner by some indexes. Here, we will implement a JavaScript program for queries for rotation and kth character of the given string in the constant time. In this article we will implement the proper code and explain each step. Introduction to Problem In the given problem, we are given by a string which contains some characters in it. We are given by some limited queries and each query contains two numbers or integers. First integer represents the number of times we have to ... Read More
