The Subset Sum Problem is a classic problem in computer science and dynamic programming. Given a set of positive integers and a target sum, the task is to determine whether there exists a subset of the given set whose elements add up to the target sum. PHP Program for Subset Sum Problem Using recursive solution Example Output Found a subset with the given sum. No subset with the given sum. In the provided example, the set is [1, 7, 4, 9, 2], and the target sums are 16 and 25. The second call with a ... Read More
Linux and macOS are two different types of operating systems. While they are similar in certain ways, they are also very different from one another. In this tutorial, we'll compare and contrast the various features of Linux and macOS and highlight how they are different from each other. We will compare their applicability in various scenarios as well as examine their advantages and disadvantages. What is Linux? Linux is an open−source, Unix−like operating system kernel that serves as the foundation for various Linux−based operating systems (distributions). It was initially developed by Linus Torvalds in 1991 and has since become ... Read More
TypeScript is a superset of JavaScript that provides static typing capabilities, allowing developers to write more reliable and efficient code. One of the most powerful features of TypeScript is its support for reflection. Reflection enables TypeScript developers to inspect and manipulate the properties of classes at runtime, making it easier to write more flexible and dynamic code. In this article, we will explore how to use TypeScript reflection to get class properties and values. We will discuss what reflection is and how it works in TypeScript, provide a brief overview of TypeScript decorators, and then walk through three examples of ... Read More
What is Rabin-Karp Algorithm? The Rabin-Karp algorithm is a string pattern matching algorithm that efficiently searches for occurrences of a pattern within a larger text. It was developed by Michael O. Rabin and Richard M. Karp in 1987. The algorithm utilizes a hashing technique to compare the hash values of the pattern and substrings of the text. It works as follows: Calculate the hash value of the pattern and the first window of the text. Slide the pattern over the text one position at a time ... Read More
TypeScript is a popular programming language that offers features such as type checking and type annotations to help developers write more robust and maintainable code. However, when TypeScript code is compiled into JavaScript, the type information is lost in a process called type erasure. This can lead to errors at runtime that are difficult to diagnose and fix. In this article, we will explore the concept of type erasure in TypeScript and how it can affect error behaviour in our code. Type Erasure Type erasure is the process of removing type information from a program during compilation. In TypeScript, this ... Read More
Linux and iOS are two very different types of operating systems. In this tutorial, we'll compare and contrast the various features of Linux and iOS and highlight how they are different from each other. We will compare their applicability in various scenarios as well as examine their advantages and disadvantages. Linux Operating System Linux is an open−source, Unix−like operating system kernel that serves as the foundation for various Linux−based operating systems (distributions). It was initially developed by Linus Torvalds in 1991 and has since become one of the most prominent and widely used operating systems in the world. Linux ... Read More
What is PHP? PHP (Hypertext Preprocessor) is a widely used server-side scripting language for web development. It allows developers to embed code within HTML files, enabling the creation of dynamic web pages and interactions with databases. PHP is known for its simplicity, versatility, and extensive integration capabilities with popular databases. It offers a broad range of extensions and has a large community of developers, ensuring ample resources and support. What is Naive Algorithm in PHP? The Naive algorithm, also known as the Brute Force algorithm, is a simple pattern searching algorithm used to find occurrences of a ... Read More

An operating system (OS) is a group of programs that controls computer hardware resources and offers standard services to software applications. It serves as a conduit between the user and the hardware. It is accountable for carrying out all procedures. There are many operating systems available for mobiles, PC, etc. Kali Linux and Parrot OS are such operating systems. The following are the differences between them. What is Kali Linux? A Debian−based Linux distribution called Kali Linux is made specifically for penetration testing and digital forensics. It is supported and upheld by information security training provider Offensive Security. Mati Aharoni ... Read More
PHP (Hypertext Preprocessor) is a popular scripting language designed for web development. It is widely used for creating dynamic and interactive web pages. PHP code can be embedded directly into HTML, allowing developers to mix PHP and HTML seamlessly. PHP can connect to databases, process form data, generate dynamic content, handle file uploads, interact with servers, and perform various server-side tasks. PHP supports a wide range of web development frameworks, such as Laravel, Symfony, and CodeIgniter, which provide additional tools and features for building web applications. PHP is an open-source language with a large community, extensive documentation, and ... Read More
