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 ...

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
Understanding iOS memory management is essential for iOS and macOS development. The concept of weak self and unowned self is challenging to understand, especially for beginners. ARC (Automatic Reference Counting) may have solved many problems for us. Swift still requires that you manage references a lot of the time when you are not working with value types. ARC or Automatic Reference Counting Automatic Reference Counting (ARC) is used for tracking and managing the app’s memory usage. In most cases, this means that memory management “just works” in Swift, and you don’t need to think about memory management yourself. ARC automatically ... Read More
The rise of digital marketing has created a whole new industry, and people are starting to embrace it as a career option. It is expected that this field will become one of the biggest in the coming years. Due to the rise of digital marketing, organizations are now recruiting digital marketers to reach their target audiences. Individuals with good skills in this field are also getting recognition and are able to earn a decent salary. While graphic designing is regarded as a specialist job, many people are still going for it because it offers them a good career opportunity. ... Read More
Introduction Non-Negative Matrix Factorization (NMF) is a supervised algorithm used to represent data into lower dimensions which reduces the number of features while preserving enough basic information to construct the original matrix from the reduced feature space. In this article, we will be going explore more about NMF and how it can be useful. Non-Negative Matrix Factorization NMF is used to reduce the dimensions of the input matrix or corpus. It uses factor analysis which gives less importance to less relevant words. The decomposition of the original matrix(which is a non-negative matrix) thus creates a product of two non-negative coefficients ... Read More
Abstract The Linux kernel is the core component of the Linux operating system, and it is responsible for managing system resources and providing various services to user space applications. Building the Linux kernel from source is a common task for developers and system administrators, and the Makefile is the primary tool used for this purpose. One of the targets provided by the Makefile is the "oldconfig" target, which is used to update the kernel configuration file based on the current system configuration. In this tutorial, we will explain the "oldconfig" target and how to use it. Note − Linux commands ... Read More
Abstract There are countless applications for the widely used and beneficial scripting language bash. Despite the fact that the language itself is widely used, testing it is not as common. This may result in expensive mistakes and reduced trust in the code. In this article, we are going to understand how to test bash scripts with the Bats in the Linux. Note − Linux commands are case-sensitive. What is BATS? Bash Automated Testing System, sometimes known as BATS, is a testing framework. Before a bash program is released, it may be verified using this automated testing procedure that it is ... Read More
Abstract On the Linux command line, cp -r can be the first command that appears when we want to copy directories recursively. Dotfiles are understood to function under Linux as hidden files. We occasionally exclude hidden files and directories from directories while copying them recursively. We'll learn how to do it in this tutorial. Note − Linux commands are case-sensitive. SCP command Using the command-line tool SCP (secure copy), you can safely move files and directories between two places. We can copy a file or directory with scp from a local system to a remote system, from a remote ... Read More
