In this article, we will write a go language program to interchange the diagonal elements of a matrix. Exchange the diagonal elements of a matrix using an external function In this program, we will write a go language program to interchange the diagonal elements of a 3 X 3 matrix using a user-defined function. Algorithm Step 1 − Import the fmt package. Step 2 − Create a function to interchange the diagonal elements of the matrix. In this function, we have defined two variables of integer type and assigned values to them. Step 3 − Use for loop ... Read More

In this tutorial, we will write an article to find the normal and trace of a matrix. A matrix is considered normal if its square root equals the sum of the squares of each member and the trace is the total of a matrix's diagonal elements. Golang Program To Find The Normal Finding Normal of 2x2 Matrix In this example, we will see how we can find the normal of a 2 X 2 matrix. Algorithm Step 1 − First, we need to import the fmt and math package. Step 2 − Create a function to find the Normal ... Read More

In this tutorial, we will see to write a go language program to find common elements in two arrays. Find Common Array Elements Using User-Defined Function The following code illustrates how we can find the common elements in two different arrays of strings. Algorithm Step 1 − import the fmt package. Step 2 − Define a function named intersection() that accepts the two arrays as arguments and returns the resultant array as an output to the function. Step 3 − Create an empty array of strings called out and a map called bucket. Step 4 − Use for ... Read More

This error is very frequent as you can see many times while writing code. Don't worry, you will understand this error in detail in this article. Before jumping to the cause of this error, let's understand what is optional in Swift. Optional Initially, when we receive a value from another source, such as the backend server, it might contain a valid value or nothing at all. In that case, you use optionals that represent a variable with two possible situations: either a value or no value at all. var possibleNumber = "450" var convertedNumber = Int(possibleNumber) In the above ...

In this article, you will learn about logging methods in the Swift language. You will also learn what the differences between them are. Debugging is the most common practice while writing code for an iOS application. It enables you to debug logic, code, errors, etc. Swift provides in-built libraries to print logs on the console. We have some options to print logs on the console like print(), println(), and NSLog(). Let's try to understand each of them. print() In Swift, print() is a function that prints a message to standard output (e.g., the console). It takes one or more arguments, ... Read More

In this article, you will learn how you can download an image from a URL in the Swift language. In the iOS application, image downloading from the image URL is the most common task. Apple provides us with a native library to download any data from any URL. There are many third-party libraries available on GitHub to download the images. But in this tutorial, we are not going to use any third-party library. We will use the URLSession class provided by Apple itself. What is the URLSession Class? URLSession is a class in the Foundation framework that provides an API ... Read More
