A rune in Golang is a representation of a Unicode code point, which is an integer number used to identify a particular character. In many programmes, it's necessary to determine whether a rune is an uppercase letter or not, and Golang has built-in functions to help with this. This article will explain how to use examples to show how to use the Golang check to see if a rune is an uppercase letter. Checking If a Rune is an Uppercase Letter In Golang, the built-in unicode package provides the IsUpper() function that can be used to check if a rune ... Read More
Developers may easily manipulate Unicode characters and symbols. Thanks to the extensive built-in functions and packages provided by the Go programming language (also known as Golang). Determining whether a rune (a Unicode code point) is a punctuation character or not is a common problem when working with strings. Commas, periods, exclamation points, and other symbols used for punctuation in many languages are examples of punctuation characters. This article will examine how to use Golang to determine whether a given rune is a Unicode punctuation character and will include sample code to show how it works. Using the "unicode" Package Golang ... Read More
A variety of built-in functions and packages are available in the Go programming language (also known as Golang), which makes it simple to work with characters and symbols in strings. Verifying a rune's (a Unicode code point) status as a symbolic character is a frequent operation when working with strings. Punctuation marks, mathematical symbols, and other non-alphanumeric characters can all be considered symbolic. In this article, we will explore how to check whether a given rune is a symbolic character or not using Golang, and we'll provide some sample code to demonstrate how it works. Using the unicode.IsSymbol() Function Go ... Read More
Go has built-in support for Unicode . In Go, a code point from Unicode is represented by the rune type. Evaluating a rune to see if it contains a space character or not is one of the frequent actions when working with strings. Several methods for determining whether a rune in Go is a space character or not will be covered in this article. Using the Unicode Package Many functions for working with Unicode characters are offered by the unicode package, which is part of the Go standard library. One of these functions is called IsSpace, which gives a result ... Read More
A Unicode code point is represented by the rune type in Go. For many string operations, including case conversion, counting the number of lowercase letters in a string, and other string operations, it is helpful to know if a rune is an uppercase letter or lowercase letter. The several approaches to determine if a rune in Go is a lowercase letter or not will be covered in this article. Using the Unicode Package Go's unicode package offers a number of functions for working with Unicode characters. One such function is IsLower, which gives a true result if the given rune ...

A rune is a Unicode code point that is used as an alias for the int32 type in Go. It is frequently employed to denote a single character within a string. We occasionally need to determine whether a rune represents a decimal digit. This article will cover how to determine in Go whether a rune is a decimal digit. Using the unicode.IsDigit() Function To work with Unicode code points, Go has the unicode package, which includes functions. To determine whether a particular rune is a decimal digit or not, use the IsDigit() function of this package. A rune can be ... Read More
In Golang, it is important to know whether a slice is sorted or not, especially when working with algorithms that require sorted data. In this article, we will explore various methods to check if a given slice is sorted or not. Using a Loop to Check if the Slice is Sorted One way to check if a slice is sorted is to use a loop to compare adjacent elements in the slice. If the elements are in ascending order, then the slice is sorted. Here is an example code − Example package main import "fmt" func isSorted(s []int) ... Read More
Presence of a specific character or group of characters in a string is a typical procedure when working with strings. Several methods for determining whether specific characters are present in a Golang string will be covered in this article. Using the strings.Contains() Function Using the built-in strings is the simplest approach to determine whether a character or substring is contained in a Golang string. the contains() function. A boolean value indicating whether the substring was discovered in the string is returned by this function, which requires two arguments: the string to search for and the substring to look for. Here ... Read More
The meaning of image classification is to extract as much information from the image as possible. For example, when you upload an image to Google photos, it extracts information from the image and suggests the location based on that. We can use OpenCV to detect every small information from the image and predict the image. Training and testing models from scratch using JavaScript requires lots of effort, and also, it requires the proper dataset containing the different images. So, in this tutorial, we will use the pre-trained model of ml5.js to classify the image. The ml5.js library contains various pre-trained ... Read More
Channels in Golang are useful for transferring data and coordinating the execution of goroutines. We will go over what channels are, how they operate, and how to use them successfully in Golang in this article. What are Channels? In Golang, channels are a means of data synchronisation and communication between goroutines. A channel primarily functions as a message queue that enables communication between goroutines. Without the requirement for explicit locking or synchronisation, channels offer a secure and effective method of data sharing between goroutines. How Channels Work Channels in Golang are implemented using the chan keyword. Channels can be created ... Read More
