In this article, we are going to discuss how we can check if a matrix is symmetric or not using C#. What is a Symmetric Matrix? A symmetric matrix is a square matrix (matrix which has the same number of rows and columns) in which the element at position A[i][j] is equal to the element at A[j][i] for all i and j. In other simple words, we can say that a matrix is called a symmetric matrix if it is a square matrix that is equal to its transpose. Below are a few examples of understanding a symmetric matrix: ...

To check if a matrix is symmetric, we simply check if the matrix and it's corresponding transpose matrix are equal. A symmetric matrix is a special case of a matrix where both the matrix and the transpose of the matrix are the same (A = A^T). In this article we are given with an array and our task is to write a JavaScript program to check if a matrix is symmetric. Users must be familiar with 2D matrix, transpose of matrix, symmetric matrix, nested loop and if/else statement. Example Input: matrix [A]: [[1, 2, ... Read More
Milliseconds is a smaller unit of time used for problems where precise time calculations are desired. We can easily convert seconds to milliseconds using Python. This is useful in many applications, such as video editing, data analysis, and real-time processing. Problem Description We are given time input in seconds and have to convert it into milliseconds. In this problem, we are going to learn how we can convert seconds to milliseconds in Python. The formula for converting seconds to milliseconds: Milliseconds = Seconds × 1000 Examples Input: 3 Output: 3000 Explanation: We know that, 1 second = 1000 milliseconds, ... Read More

In JavaScript, sometimes we need some specific key-value pairs from an object. Suppose we have a large object and only want to select some specific keys. In this article, we will learn how to filter the keys of an object using Lodash. What is Lodash? Lodash is a popular JavaScript library that provides 200+ functions to facilitate web development. It provides helper functions like map, filter, and invoke as well as function binding, javascript templating, deep equality checks, creating indexes, and so on. Lodash can be used directly inside a browser and also with Node.js. Lodash Installation There are ... Read More
In this article, we’ll learn to find the largest of three numbers using the ternary operator in Java. This simple yet effective approach allows you to write concise and readable code. Finding the largest of three numbers is a common programming task, and Java provides an efficient way to do this using the ternary operator. This concise approach reduces code complexity while maintaining readability. What is the Ternary Operator in Java? The ternary operator is a shorthand for if-else statements in Java. It uses the syntax: condition ? value_if_true : value_if_false This operator is useful for simple conditional checks and ... Read More
In this article, we will learn about the Signature.getInstance() method, how it works, and examples that demonstrate its usage. A signature object that can implement the required signature algorithm can be obtained using the method getInstance(). The Signature.getInstance() method in Java is a crucial component of the Java Cryptography Architecture (JCA). It is part of the java.security package and is used to create and manage digital signatures. Java Cryptography Architecture (JCA) The Java Cryptography Architecture (JCA) is a collection of APIs designed to implement modern cryptographic concepts like digital signatures, message digests, and certificates. It provides developers with tools to ... Read More
In this tutorial, we will be discussing a program to understand File Handling through C++ classes. What's File Handling? File handling is an important concept in programming, which allows a program to read from and write to files. C++ has built-in classes and functions for file handling, which is done using file stream classes that are part of the library. The most common file stream classes in C++ are ofstream, ifstream, fstream. ofstream: This class is used for output file streams, where it allows the user to write data to files. ... Read More
Linux is known for its stability, security, and flexibility, and is widely used in enterprise environments. However, as with any operating system, it is important to keep an eye on system performance to ensure that everything is running smoothly. This is where it becomes essential to monitor the users and processes in real time. In this article, we will show how you can monitor Linux users and processes in real time. We'll cover some of the most popular commands used for this purpose such as w, who, last, top, htop. In addition, we will also highlight how to use these ... Read More
