In Haskell, we can use mapM and ForM functions to print pyramid-patterned stars. A pyramid star pattern is a design or arrangement of stars or other symbols in the shape of a pyramid. It is created by printing stars or symbols in multiple rows, starting from the top and moving downwards. Each row contains one more symbol than the previous row, creating the illusion of a triangular shape. The pattern is usually symmetrical, with the number of stars or symbols in each row equal to the row number, and the middle of each row lined up vertically. Algorithm Step ... Read More

In Golang, a byte array is a sequence of bytes, and a string is a sequence of Unicode characters. Sometimes, you may need to convert a zero-terminated byte array to a string. This can be useful when working with data that is in the form of a byte array, but needs to be processed as a string. In this article, we will learn how to convert a zero-terminated byte array to a string in Golang. Understanding Zero-Terminated Byte Arrays A zero-terminated byte array, also known as a C-style string, is a sequence of bytes that ends with a null byte ... Read More

In Golang, a string is a sequence of Unicode characters. Sometimes, you may want to convert a string to lowercase, which means converting all the letters to their lowercase equivalents. This can be achieved using various methods in Golang. In this article, we will learn how to convert a string to lowercase using different approaches. Using strings.ToLower() The easiest and most common method to convert a string to lowercase in Golang is by using the strings.ToLower() function. This function converts all the ASCII letters in a string to their lowercase equivalents. Here's how to use it to convert a string ... Read More

In Golang, a byte slice is a sequence of bytes. A slice of bytes can be created using the built-in function []byte(). Sometimes, you may want to convert a slice of bytes to uppercase, which means converting all the letters to their uppercase equivalents. This can be easily achieved using the bytes.ToUpper() function or the strings.ToUpper() function. In this article, we will learn how to convert a slice of bytes to uppercase in Golang. Using bytes.ToUpper() The bytes.ToUpper() function converts all the ASCII letters in a slice of bytes to their uppercase equivalents. Here's how to use it to convert ... Read More

In Golang, a byte slice is a sequence of bytes. A slice of bytes can be created using the built-in function []byte(). Sometimes, you may want to convert a slice of bytes to title case, which means capitalizing the first letter of every word. This can be easily achieved using the strings.Title() function. In this article, we will learn how to convert a slice of bytes to title case in Golang. Using strings.Title() The strings.Title() function converts the first letter of each word in a string to uppercase. Here's how to use it to convert a slice of bytes to ... Read More

In Golang, a byte slice is a sequence of bytes. A slice of bytes can be created using the built-in function []byte(). Sometimes, you may want to convert a slice of bytes to lowercase. This can be easily achieved using the bytes.ToLower() function. In this article, we will learn how to convert a slice of bytes to lowercase in Golang. Using bytes.ToLower() The bytes.ToLower() function converts a slice of bytes to lowercase. Here's how to use it − Example package main import ( "bytes" "fmt" ) func main() { ... Read More

In Go, a string is a sequence of Unicode characters. Each character in a string is represented by a Unicode code point, which is a unique integer value assigned to each character in the Unicode standard. Runes in Go are simply an alias for the int32 type, used to represent a Unicode code point. In this article, we'll discuss how to check for a specified rune in a Golang string. Checking for a specified rune in a Golang string is relatively simple. We can use the strings.IndexRune function to check if a specific rune is present in a given string. ... Read More

In Golang, checking string equality is a common task that developers come across when building applications. However, when dealing with strings that contain characters with different case representations in Unicode, it can become a little complicated. Unicode case folding is the process of transforming characters to a common case representation to simplify case-insensitive comparisons. In this article, we will explore how to check string equality under Unicode case folding in Golang. What is Unicode Case Folding? Unicode case folding is a process that converts characters to a common case representation to simplify case-insensitive comparisons. In Unicode, some characters have more ... Read More

In Golang, structs are an essential part of the language and are used to define complex data types. Often, you may find yourself in a situation where you need to add a method to a struct to perform some specific action. In this article, we will discuss how to add a method to a struct type in Golang and provide some examples to help you understand the concept. Defining a Struct in Golang Before we dive into adding methods to a struct, let's first understand how to define a struct in Golang. A struct is a composite data type that ... Read More

As a popular programming language, Golang is used in many applications and frameworks due to its high performance and easy-to-use syntax. If you are working with interfaces in Golang, you may need to access the fields of the interface to retrieve or manipulate data. In this article, we will discuss how to access interface fields in Golang and provide some examples to help you understand the concept. Understanding Interfaces in Golang Before we dive into accessing interface fields, let's first understand what interfaces are in Golang. An interface is a set of method signatures that define a behavior. In other ... Read More
