In this program, we are given two linked lists and we have to create a new linked list that will contain all the elements which are common in both of the lists as the lists are given sorted then we can use the concept of two pointers which are going to see in the article below. Introduction to Problem In the given problem we have to find the intersection of the given linked lists. Intersection means to get the common values from the given set of values, so here we have given two sorted linked lists from which we have ... Read More

In this article, we are going to implement a JavaScript program for finding a triplet from three linked lists with a sum equal to a given number. This problem is a kind of variation of the standard and famous three-sum problem but in a linked list manner. Let’s see the problem and implement its code along the key points of the problem. Introduction to Problem This problem is the variation of the standard problem of three sums where we are given three arrays and we have to find if there is any triplet present in the array with a sum ...

A binary matrix is a matrix that consists of only two digits as its name suggests and those two digits are 1 and 0. In this article, we will go through the code with the approach and the proper explanation to understand the concepts in a better way. In this tutorial, we are going to write a JavaScript program for counting the sets of 1s and 0s in a given binary matrix. Introduction to Problem In this problem, we are given a binary matrix and we have to find the sets that contain the same value in the row or ... Read More

Counting the frequencies means we have to count the number of times an element from the array appears in the given array. We can use some inbuilt data structures like maps to get the frequency or we can sort the array also to get the frequency of the array elements. We will discuss both approaches, let’s see both of them one by one − Sorting the Array In this approach, we are going to sort the array and check if the current element is the same as the previous one, if the current array is not the same then this ...

Prime numbers are numbers that have exactly two perfect divisors. We will see two methods to find the number of prime numbers in a given range. The first is using the brute force method and by this method time complexity is a bit high. Then we will improve this method and will go for the Sieve of the Eratosthenes algorithm to go with better time complexity. In this article, we are going to find the total number of prime numbers in the given range using the JavaScript programming language. Brute Force Method In this method first, we will learn how ...

In this article, we will go through a JavaScript program to check whether all the rotations of a given number are greater than or equal to the given number or not. We will write an algorithm and explain every step that what we are doing. The time complexity of the code that is going to discuss will be optimistic and space complexity will all be improved from one code to another. Introduction to Problem In the problem, we are given a number and we have to check for each rotation whether they all are greater than the current number or ... Read More

The basic structure of a Linked List in JavaScript can be created using the class in JavaScript and then the movement of the nodes from one position to another can be done for rotation. In this article, we will learn how to rotate a linked list in a clockwise manner in JavaScript programming language. We will see the code for understating the concepts in deep. In the given problem we have given a linked list and we have to rotate it in a clockwise manner. This means, we have to put the last element in first place in every move ... Read More

Memoization is a helper function, or we can say a technique for improving the efficiency of a program by Keeping track of the values that the function has already calculated in the past. In this article, we will discuss the Memoization Helper function with different examples and discuss all the examples in detail so that we can get a better understanding of Memoization. Now let’s discuss the Memoization helper function in the deep in the below section and also see their implementation with an explanation. Introduction to Memoization Helper Function Memoization is a technique of programming that is used to ... Read More

ES6 is referred to as ECMAScript 6. ES6 is the sixth version of ECMAScript, which was released in 2015 and is sometimes known as ECMAScript 2015. ECMAScript was developed to standardize JavaScript. Further in this article, we are going to discuss Handler Methods in ES6 in detail. Introduction to ES6 As we Know ES6 (ECMAScript 6) is introduced for the standardization of JavaScript. It is a programming language and in ES6 we don't have to need to write a number of lines of code or we can say we have to write less and accomplish more. JavaScript follows the ES6 ... Read More
