JavaScript Program for the Number of local extrema in an array is a common problem in the field of computer science and data analysis. Local extrema are the peaks and valleys in a sequence of numbers. In this article we are having two arrays, our task is to write a Javascript program for number of local extrema in an array. Example Input: arr1 = [1, 2, 3, 2, 1, 4, 5, 6, 5, 4, 3, 2, 1]; First local extrema: 3, {2 < 3 > 2} Second local extrema: 1, {2 > 1 < 4} Third local ... Read More

To write a javascript program for mirror of matrix across diagonal, we will be discussing two approaches with their code example and explanation of code. In this article we are having a 2D matrix. Our task is to write a JavaScript program for mirror of matrix across diagonal. Example Input: matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] Output: [[1, 4, 7], [2, 5, 8], [3, 6, 9]] Approaches ...

JavaScript Program for Minimum product subset of an array is a common problem that arises in the field of computer science and programming. The problem statement requires us to find the minimum product that can be obtained from any subset of the given array. A minimum product subset of an array is a subset of array elements that yields the smallest possible product. Several algorithms are available for identifying this subset, including dynamic programming, greedy algorithms, and branch and bound. The selection of the algorithm is determined by the particular constraints and specifications of the problem at hand. In this ... Read More

Cascading Style Sheets (CSS) is a powerful component of web development which enables the developers to determine the visual appearance of their websites. In CSS, classes are used as selectors which enables us to apply several specific styles to an element. You can also use multiple classes for a particular element. However, when you apply multiple classes to an element, it is necessary to know how to specify the order of these classes in which they will be rendered to avoid discrepancies and unexpected results. In this article, we will discuss different methods to specify the order of classes ... Read More

The Paradoxical effect is a visual effect which is used to create optical illusion of any object, element or text that appears to move in a contradictory way. This effect can be used to add interesting and unique element to your web page. This can be easily created using HTML and CSS. In this article, we will discuss about the techniques and properties which is required for creating Paradoxical effect using CSS. We will start creating simple paradoxes using combination of two CSS properties simultaneously, and then dive into more advanced techniques which enables us to create complex paradoxical ...

To apply multiple transform property to an element using CSS, we will be using two different methods which uses transformation property. In first approach we will be using two function of transform property whereas in second method we will be using nested class to apply different transformations. In this article, we are having a container with background image and our task is to apply multiple transform property to an element using CSS. Methods to Apply Multiple Transform to an Element Applying Multiple Transform Values Applying Multiple Transformation using Nesting of ... Read More

In web development, CSS (Cascading Style Sheets) enables the developers to determine the visual appearance and layout of a website. However, since different web browsers have varying levels of support mechanism for CSS, it can result in inconsistency while rendering the web pages by the compiler. To overcome this compatibility issue, developers often opt for using CSS hacks to ensure that their web pages are displayed consistently across different browsers and devices. One such hack is the star-preceded property (also known as star property hack), which is used to target specific versions of Internet Explorer (IE) that have limited support ... Read More

Tabs are created to implement multipage views in apps. Tabs are often placed on the top or at the bottom of the screen. Some libraries permit making tabs in mobile apps. Tabs can use icons instead of text type of labels. In this article, the React native and javascript code is shown with two different examples where in the first example, createMaterialBottomTabNavigator from '@react-navigation/material-bottom-tabs' is used to make tabs and then rendering these as labels. In the other example, the icons from Ionicons are used to make tabs and then render these on the screen of the device. Algorithm-1 Step ... Read More
