Job, task, and process are three terms that are used to refer to the work being done in different types of operating systems. In this article, we will have a detailed study of these three terms and how they are different from each other. What is a Process? A program being run is known as a process. A process is referred to as a set of instructions. The process is an active entity, whereas the program is a passive one. When we run a program, it stays on our system's hard drive, and once it enters the main memory, it ... Read More
What is palindrome? A palindrome is a word, phrase, number, or sequence of characters that reads the same backward as forward. In other words, it remains unchanged when its characters are reversed. Example "level" is a palindrome because it reads the same from left to right and right to left. "racecar" is a palindrome. "12321" is a palindrome. "madam" is a palindrome. PHP Program for Longest Palindromic Subsequence ... 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. PHP Program for Largest Sum Contiguous Subarray 4+ (-1) +2 +1 = 6 Maximum contiguous sum is = 6 Using Kadane's Algorithm Kadane's Algorithm is an ... 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. iOS and Android are such operating systems. The following are the differences between them. What is iOS? The iPhone operating system is referred to as iOS. It was developed by Apple Inc. in 2007. Following its initial 2007 release for the first−generation iPhone, the iOS operating system has since been ... Read More
What is Pagination? Pagination in PHP refers to the process of dividing a large set of data into smaller, more manageable sections called "pages." It is commonly used in web applications to display a limited number of records or results per page, allowing users to navigate through the data easily. Pagination is essential when dealing with large data sets because displaying all the records on a single page can lead to performance issues and an overwhelming user interface. By implementing pagination, you can improve the user experience and optimize the performance of your application. PHP program to ... Read More
TypeScript is an open-source programming language developed and maintained by Microsoft. It is a superset of JavaScript, which means that all valid JavaScript code is also valid TypeScript code. TypeScript adds optional static typing, classes, interfaces, and other features to JavaScript to improve code quality, maintainability, and scalability. In this article, we'll explore how TypeScript is an optionally statically typed language, what that means for developers, and how it can benefit them in their projects. What is Optional Static Typing? Static typing is a programming language feature that allows developers to define data types for variables, function parameters, and function ... Read More
Inheritance: Inheritance is a fundamental concept in object-oriented programming (OOP) that allows classes to inherit properties and behaviors from other classes. It is a mechanism for creating new classes based on existing classes, promoting code reuse and establishing hierarchical relationships between classes. Inheritance is based on the concept of a "parent-child" or "superclass-subclass" relationship. The class from which another class inherits is called the superclass or base class, while the class that inherits from the superclass is called the subclass or derived class. The subclass inherits all the properties (variables) and methods (functions) of its superclass and can also ... Read More
TypeScript, a superset of JavaScript, offers static typing capabilities that enhance code quality and catch errors during compilation. To fully leverage TypeScript's static typing features, it's crucial to have type definition files (.d.ts) for external JavaScript libraries and modules used in projects. These type definition files describe the types and interfaces exposed by the external entities, enabling the TypeScript compiler to understand their shape and behaviour. In this article, we'll explore the step-by-step process of creating custom TypeScript type definition files, empowering developers to benefit from static typing in their projects. Prerequisites Type definition files (.d.ts) serve as an interface ... Read More
TypeScript, an extension of JavaScript, introduces modules as a means to structure and organize code effectively. Modules play a vital role in developing scalable and maintainable applications by enabling code encapsulation and reusability. TypeScript supports two types of modules: internal (namespaces) and external (ES modules). In this article, we will delve into the differences between internal and external modules in TypeScript, exploring their characteristics and impact on code organization and sharing within a project. Internal Modules Internal modules, also known as namespaces, serve as logical containers within a single file to group related code elements together. They offer benefits such ... Read More
Many Android applications have the zoomable scrolling feature, which enables users to pinch or stretch their fingers on the screen to zoom in and out of material like photographs or maps. Using a Zoom Scroll View, a custom view that expands the Android ScrollView and offers built-in support for zooming and scrolling, is one popular method for implementing zoomable scrolling in Android. We shall examine how to implement Zoom Scroll View on Android in this technical writing. In this tutorial, we'll go through the fundamental ideas and procedures needed to develop zoomable scrolling in your Android application using a Zoom ... Read More
