A matrix is an arrangement of numbers in rows and columns. A matrix has two diagonals i.e. Right diagonal and Left diagonal. So here we calculate the sum of the right diagonal of the square matrix using Swift Programming. For example, we have the following matrix − Matrix = 3 4 5 5 3 2 1 8 1 The right diagonal elements are 5, 3, 1. So the sum of right diagonal is 9(5+3+1). Algorithm Step 1 − ... Read More
To check if the given string is numeric or not we use Double() initializer in Swift Programming. A string is an ordered collection of characters for example “Sky”. A string can be numeric and non-numeric. A numeric string is a string which only contains numbers for example “12345”. So the valid numeric strings are: “3423”, “222333”, “34.342”, etc., whereas non-valid numeric strings are “23hfd23”, “423131sdd”, etc. So it converts the given string into double and return true if the given string is numeric otherwise return false. Algorithm Step 1 − Create a function Step 2 − Return ... Read More
In this article, we will learn how to write a swift program to convert an array into a string and join elements with a specified character. An array is used to store elements of same data type in an order. Here we use the following methods to join elements of the array with a specified character − Using joined(separator:) function Without using inbuilt function Method 1: Using joined(separator:) Function So to convert an array into a string and join elements with a specified character we use joined(separator:) method. This method is used to concatenate the elements of the ... Read More
Swift has various functions like flatmap(), compactmap(), reduce() to flatten an 1D array. An array is used to store elements of same data type in an order whereas a set is used to store distinct elements of same data type without any definite order. Method 1: Using flatmap() Function To flatten 2D array into 1D array we can use flatmap() function. The flatmap() function return an array by concatenating the sub arrays into a single array. Syntax func flatMap{_res} Here, res is a closure which accepts the element of the specified array as its argument and return a flattened ... Read More
In swift, we have various methods like Array() initializer and for-in loop that can be used for getting the subarray from an array using a specified range of indices. An array stores elements of the same data type in an order. Let’s understand both the methods in detail in this article. Method 1: Using Array() initialiser To get the subarray from an array using a specified range of indices we uses Array() initialiser. Here we find the subarray using range operator and then convert the elements into the array using Array() initialiser. Algorithm Step 1 − Create an ... Read More
Python, a versatile and powerful programming language, has gained immense popularity for its ease of use and extensive libraries. One such library is Tkinter, which provides a simple and intuitive way to create graphical user interfaces (GUIs) in Python. Tkinter offers a range of built−in widgets and features, allowing developers to design interactive applications that enhance user experience In this tutorial, we will explore various methods to customize the color of the Tkinter menu bar. The menu bar, located at the top of the application window, provides a convenient way to access different functionalities and options. By default, Tkinter menu ... Read More
Vinyl and linoleum are two popular flooring options that have been around for quite some time. Both of these materials are made from synthetic materials and offer several benefits over traditional flooring materials such as wood or stone. Despite their similarities, there are some fundamental differences between vinyl and linoleum, which can make one option more suitable than the other based on specific requirements. What is Vinyl? Vinyl and linoleum are two types of flooring materials that are commonly used in both residential and commercial settings. While they may appear similar, they have distinct characteristics, compositions, and installation methods. Vinyl ... Read More
In web development, it's crucial to create applications that respond quickly to user actions. However, certain tasks like sending emails or processing large data can slow down an application. That's where Celery integration with Django comes into play. Celery is a powerful tool that accelerates Django applications by handling time−consuming tasks in the background. In this article, we'll explore how Celery works with Django and enhances your web application's performance. Whether you're new to Django or an experienced user, this article will guide you in leveraging Celery to build faster and more efficient web applications. Let's dive in and uncover ... Read More
In this tutorial, we will explore the process of building smart contracts and decentralized applications (DApps) using Python. Smart contracts are self−executing contracts with predefined rules and conditions that automatically execute when the conditions are met. DApps, on the other hand, are applications that run on a decentralized network, utilizing smart contracts for their functionality. In this article, we will cover the technologies and tools required for developing smart contracts and DApps in Python. We will then proceed with step−by−step instructions, accompanied by code snippets and their explanations, to demonstrate how to create and interact with smart contracts, as well ... Read More
