Mastering Kotlin Generics: Understanding and Deep Dive of In, Out, and Where

Kotlin, a modern statically typed programming language, offers many powerful features to streamline coding, one of which is its support for generics. Generics enable you to write flexible and reusable code, allowing types to be parameters when defining classes, interfaces, and functions. Understanding the intricacies of generics is crucial for leveraging Kotlin's full potential. In this blog, we'll delve into the concepts of in , out , and where in Kotlin's generics. What Are Generics? Generics are a feature that allows you to define classes, interfaces, and methods with placeholder types. This way, you can create more flexible and reusable components. For instance, you can create a List<T> that can hold any type T , rather than creating separate classes for each type. class Box<T>(val value: T) fun main() { val intBox = Box(1) val stringBox = Box("Hello") } In this example, Box<T> is a generic class where T

How Google Search Works? : The Magic Behind the Search Box

When you type a query into the Google search box, it may seem like magic that you receive highly relevant results in just a fraction of a second. But behind that simple search bar lies a complex and sophisticated system. Let's dive into how Google Search works, from crawling and indexing to ranking and delivering results. 1.

These bots follow links from one page to another, discovering new and updated content along the way. The goal is to cover as much of the web as possible and gather fresh information. Googlebot starts by fetching a few web pages, and then follows the links on those pages to find new URLs. This process is continuous and ensures that Google's database stays current with the ever-changing internet. 2. Indexing: Organizing the Information Once the web pages are
