In this program, we are given an array of integers or elements and we have to return the element which presents the least numbers of the time in the array, and if there is more than one least frequent number present we can return any one of them which we ... Read More

In this program, we will be given a linked list that may consist of a loop and we have to find if the loop exists then what will be the size of the loop. Let’s a very famous approach to finding the length of a loop with the help of ... Read More

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 ... 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 ... Read More

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 ... Read More

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 ... 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 ... 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 ... Read More
