An array is a linear data structure used to store the different types of objects and we are given an array of size n and an integer k (where k is the number by which we will rotate an array). We will rotate the array by k elements and then ... Read More

The linked list is a linear data structure that consists of nodes, and each node is stored in memory in a non-contiguous manner. Nodes are connected by storing the address of the next node. We are given a linked list that will contain some integers in a random manner and ... Read More

Linked list is linear data structure and we have given a sorted linked list that consists of the integers. There are some numbers that may be duplicated or repeated and we have to remove them. As the given linked list is sorted, we can simply iterate over it and by ... Read More

We are given an array that will contain integers and another array will be given that will contain the queries and each query represents the range that we are given by the leftmost and the rightmost index in the array and an element. For that range or the subarray, we ... Read More

To understand the class methods in CoffeeScript first we need to understand what it is CoffeeScript. CoffeeScript is a lightweight programming language, and this language compiles in JavaScript and is also inspired by languages like JavaScript, python, ruby, Haskell, etc. Further, we will discuss it in detail after that we ...

In this article, we will implement the JavaScript program for the Maximum sum of i*arr[i] among all the rotations of the given array. Here i*arr[i] expression indicates that we have to maximize the sum of all the elements of the array by taking the product of them with the current ... Read More

A subarray is part of an array formed by removing some or no prefixes of the array and removing some or no suffix elements of the given array. We will try to find the subarray that will contain the elements, and by multiplying all of them, we can get the ... Read More

In this article, we are going to implement a JavaScript program for Maximizing elements using another array. We are given two arrays and have to pick some elements from the second array and replace the elements of the first array. We will see the complete code to implement the concepts ... Read More

A matrix is a kind of 2-D array, which is in the form of some number of rows, and for each row, there is the same number of columns and by the row and column number, we can get the element at any particular index. For the Markov matrix, each ... Read More

We will implement a code to find the longest subsequence of a given number that has the same left and right rotation in the JavaScript programming language. The left and right rotation of a given number means, for left rotation we have to move the left-most digit of the number ... Read More
