In Haskell we can check whether a given number is Armstrong or not using list comprehension and sum function. Armstrong numbers, also known as narcissistic numbers, are numbers such that the sum of the cubes of their digits is equal to the number itself. For example, the number 153 is an Armstrong number because 1^3 + 5^3 + 3^3 = 153. Algorithm Step 1 − The armstrong function calculates the sum of the cubes of the digits of n using list comprehension and the sum function, and define Step 2 − Program execution will be started from main function. ...

Interfaces in Golang are an integral part of the language's design philosophy. They enable polymorphism, which is the ability to create objects with different underlying types but with common behavior. However, sometimes a struct needs to implement multiple interfaces. This is where multiple interfaces come into play. In this article, we'll explore the concept of multiple interfaces in Golang, how to implement them, and their practical applications. What are Multiple Interfaces in Golang? In Golang, a type can implement multiple interfaces. When a struct implements multiple interfaces, it gains access to all the methods of those interfaces. This means that ... Read More

In computer programming, goroutines are lightweight threads that allow for concurrent execution of code in a single process. Goroutines are a key feature of the Go programming language, which was developed by Google in 2009. In this article, we'll explore the concept of multiple goroutines and how they can be used to improve the performance of your applications. What is a Goroutine? A goroutine is a function that is executed concurrently with other goroutines in a single Go process. Goroutines are similar to threads, but they are much lighter and more efficient. When a goroutine is created, it is assigned ... Read More

Go programming language allows multiple methods with the same name, as long as they are defined on different types. This feature is known as method overloading. In this article, we will discuss how to implement methods with the same name in Go and their usage. What are Methods in Golang? Methods in Go are functions that are associated with a specific type. They allow us to define behavior for a particular type. Methods can be defined on both user-defined types and built-in types. Syntax of Methods in Go func (t Type) methodName(parameterList) (returnType) { // Method body ... Read More

In Go, methods are functions that are associated with a specific type. They allow developers to define behavior for objects of that type. In this article, we will explore the basics of methods in Go, how to define and use them, and the different types of methods available. Defining Methods in Golang In Go, methods are defined by associating them with a type using the following syntax − func (receiver type) methodName(parameters) returnType { // method body } The "receiver" is the type that the method is associated with. It can be a value or a ... Read More

Matching using regular expressions, or regex, is a common task in programming. Go, also known as Golang, provides a built-in package called "regexp" that allows developers to use regular expressions in their programs. In this article, we will explore how to use regular expressions in Go and the different functions and methods available in the "regexp" package. What is Regular Expression? A regular expression, or regex, is a sequence of characters that define a search pattern. Regular expressions are used to search, replace, and manipulate text. They are a powerful tool for text processing and data validation. Using Regexp in ... Read More

Loop control statements are used in programming languages to control the flow of loops. These statements help developers to execute certain conditions during loop execution. Go, also known as Golang, is a popular open-source programming language that provides three loop control statements: break, continue, and goto. In this article, we will explore each of these statements in detail and their usage in Go. The Break Statement The break statement is used to terminate a loop prematurely. It is usually used when a specific condition is met, and there is no need to continue iterating. The following example shows the usage ... Read More

The inverse error function (erf⁻¹) is the inverse function of the error function (erf) which is used to calculate the probability of a normally distributed random variable falling within a certain range of values. In this article, we will discuss how to calculate the inverse error function of a given number using Golang. Understanding the Error Function Before we dive into the inverse error function, it is important to understand what the error function is and how it works. The error function is defined as − erf(x) = (2/√π) ∫₀ ˣ e⁻ᵗ² dt This function is used to ... Read More

Interfaces in Golang are a powerful feature that allows developers to define a set of methods that must be implemented by any type that satisfies that interface. Interfaces help to make code more modular, reusable, and easier to maintain. In this article, we will explore interfaces in Golang, how to create them, and how to use them effectively. What are Interfaces in Golang? An interface in Golang is a collection of method signatures that define a set of behaviors that a type must support to satisfy that interface. In other words, an interface defines what methods a type must have ... Read More

Go is a popular programming language that is designed to be efficient, readable, and simple. One of the key features of Go is its ability to manage external packages and dependencies, which is done through the use of import statements. In this article, we will discuss the basics of importing packages in Go, and how to use them in your programs. What is an Import Statement in GoLang? In Go, an import statement is used to access external packages or dependencies in your code. An import statement specifies the name of the package you want to import and the location ... Read More
