If you're working with runes in Golang, you may need to map them to a specified case. This can be useful when dealing with text that contains both uppercase and lowercase characters, or when you need to convert text to a specific case for formatting purposes. In this article, we'll go over how to map a rune to a specified case in Golang, and provide some helpful tips for optimizing your code. What is a Rune in Golang? Before we get into mapping runes to a specific case, it's important to understand what a rune is in Golang. In Golang, ... Read More

In Go, runes are used to represent Unicode code points, and they are often used in text processing applications. In some cases, you may need to convert a rune to its lowercase representation. In this article, we will discuss how to map a rune to lowercase in Go. Mapping a Rune to Lowercase in Go In Go, you can use the unicode.ToLower() function to convert a rune to its lowercase representation. The ToLower() function takes a single parameter, which is the rune that you want to convert to lowercase, and returns the lowercase version of the rune. Example Here is ... Read More

Byte slices are an important data type in Go that allow you to work with binary data. In many cases, you will need to join the elements of a byte slice to create a single string. In this article, we will discuss how to join the elements of a byte slice in Go. Joining the Elements of a Byte Slice in Go In Go, you can join the elements of a byte slice using the bytes.Join() function. Here is the syntax for using bytes.Join() − func Join(s [][]byte, sep []byte) []byte where s is a slice of byte slices, ... Read More

Arrays are a fundamental data structure in Go that allow you to store a fixed-size sequence of elements of the same type. One of the most common operations you will perform on an array is to iterate over its elements to process them in some way. In this article, we will discuss how to iterate over an array using a for loop in Go. Iterating Over an Array Using a for loop in Go In Go, you can iterate over the elements of an array using a for loop. Here is the syntax for iterating over an array using a ... Read More

In Go, a struct is a composite data type that groups together zero or more values of different types. Structs can be created in several ways, including using the new keyword. In this article, we will discuss how to instantiate a struct using the new keyword in Go. What is the new keyword in Go? The new keyword in Go is a built-in function that allocates memory for a new value of a specified type and returns a pointer to it. The allocated memory is set to zero, which means that the new value will have its zero value for ... Read More

In Golang, struct pointers are used to create a pointer to a struct, which allows for more efficient memory management and manipulation of struct fields. In this article, we will discuss how to instantiate a struct pointer using the address operator in Golang. Step 1: Define the Struct The first step in instantiating a struct pointer is to define the struct itself. For example, let's define a simple struct representing a person with a name and age − type Person struct { name string age int } Step 2: Create a Struct ... Read More

In Golang, generating random numbers is a common task for many developers. While there are various methods for generating random numbers, it is important to use the correct type of number for your particular use case. In this article, we will focus on generating Uint64 type random numbers in Golang. Step 1: Importing the Math/rand Package To generate random Uint64 numbers, we need to import the "math/rand" package into our Golang program. This package contains a set of functions for generating pseudo-random numbers. Step 2: Setting the Seed The next step is to set the seed for the random number ... Read More

In Golang, generating random numbers is a common task for many developers. While there are various methods for generating random numbers, it is important to use the correct type of number for your particular use case. In this article, we will focus on generating Uint32 type random numbers in Golang. Step 1: Importing the Math/rand Package To generate random Uint32 numbers, we need to import the "math/rand" package into our Golang program. This package contains a set of functions for generating pseudo-random numbers. Step 2: Setting the Seed The next step is to set the seed for the random number ... Read More

When working with numbers in programming, it's often necessary to convert between different number bases, such as decimal, binary, and hexadecimal. In Go, you can easily convert a number to a string representation in a specified base using the strconv package. In this article, we'll explore how to get the string in a specified base in Golang. Step 1: Convert the Number to a String The first step to getting the string in a specified base in Go is to convert the number to a string using the strconv package. The strconv.Itoa() function can be used to convert an integer ... Read More

A random permutation of integers is a sequence of integers that has been shuffled randomly. Generating a random permutation is a common task in programming, and Go provides a built-in package for generating random permutations of integers. In this article, we will explore how to generate a random permutation of integers in Go. Step 1: Create an Integer Slice The first step to generating a random permutation of integers in Go is to create a slice of integers. You can create a slice of integers using the make function and specifying the length of the slice. slice := make([]int, length) ... Read More
