An overlapping area is an area that is shared by two objects. In the case of rectangles, it is the area of the rectangles that belong to both rectangles. In order to find the total areas of two overlapping rectangles, first er need to add the area of both rectangles respectively but in this total, the overlapping area is counted twice. Thus we need to subtract the overlapping area too. Problem Statement Given the bottom left and top right vertices of two rectangles. Find the total area covered by the two rectangles. Sample Example 1 Input bl_x1 = 0 bl_y1 ... Read More

Functional Reactive Programming (FRP) is a powerful paradigm that combines functional programming concepts with reactive programming. By leveraging FRP, developers can build highly responsive and scalable applications by modeling the flow of data and events as streams of values. JavaScript, being a widely used language for web development, can benefit from FRP through libraries and frameworks. One popular library is RxJS (Reactive Extensions for JavaScript), which provides a rich set of tools for implementing FRP in JavaScript. In this article, we will explore advanced techniques of Functional Reactive Programming using JavaScript and RxJS. Understanding FRP and Reactive Programming Before diving ... Read More

An image can be included in a web page using the HTML img> tag. The tag has no ending tag, is empty, and simply includes attributes. A web page can have scrollable text or images from left to right or vice versa, or from top to bottom or vice versa, by using the HTML container tag "marquee" . The new HTML version, HTML 5.1, however, deprecates the use of this tag. We can also use simple html properties for the same. We will look on more ways to move the image using the CSS properties as well as various ... Read More
