In Golang, trimming a string means removing whitespace characters from the beginning and/or end of the string. Trimming can be useful when working with user input, where leading or trailing whitespace may be unintentionally entered. In this article, we will explore how to trim a string in Golang. Using the strings.TrimSpace() function Golang provides a built-in strings package that contains many useful functions for working with strings. The strings.TrimSpace() function can be used to trim leading and trailing whitespace from a string. Example Here is an example of using the strings.TrimSpace() function to trim a string − package main ... Read More
In Golang, splitting text using regular expressions (regex) is a powerful and flexible way to extract information from strings. In this article, we will explore how to split text using regex in Golang. Using the regexp.Split() function Golang provides a built-in regexp package that allows us to work with regex expressions. The regexp.Split() function can be used to split a string based on a regex pattern. Example Here is an example of using the regexp.Split() function to split a string using a regex pattern − package main import ( "fmt" "regexp" ) ... Read More
Go is a powerful programming language that comes with built-in support for maps. Maps are unordered collections of key-value pairs, and sometimes it's necessary to sort them by either their keys or values. Fortunately, Go provides a way to sort maps by both keys and values using the sort package. In this article, we'll discuss how to sort a Golang map by keys or values. Sort Golang Map By Keys To sort a Golang map by keys, we first need to extract the keys from the map and sort them using the sort package. We can then iterate over the ... Read More
When sorting slices of data in Go, sometimes it's important to maintain the original order of elements that have the same sort key. This is where stable sorting comes into play. A stable sort algorithm ensures that the order of elements with the same sort key remains the same after sorting. Go provides a built-in sort package that includes a stable sorting algorithm. In this article, we will discuss how to sort a slice stably in Go. The sort package in Go provides two functions for sorting slices: sort.Slice() and sort.SliceStable(). The sort.Slice() function sorts a slice of values based ... Read More
Sorting a slice of int values is a common task in many applications, and Go provides a built-in package sort that includes functions to sort slices of any type, including slices of int values. In this article, we will discuss how to sort a slice of int values in Golang. To sort a slice of int values in Go, we can use the sort.Ints() function provided by the sort package. Here's an example of how to use this function − Example package main import ( "fmt" "sort" ) func main() { ... Read More
In Go programming language, sorting a slice of float64 values is a common task in many applications. Fortunately, Go provides a built-in package sort that includes functions to sort slices of any type, including slices of float64 values. In this article, we will discuss how to sort a slice of float64s in Golang. To sort a slice of float64 values in Go, we can use the sort.Float64s() function provided by the sort package. Here's an example of how to use this function − Example package main import ( "fmt" "sort" ) func ... Read More
In Go programming language, a slice is a dynamic array that can hold a sequence of elements of the same type. Slices can be sorted using the built-in sort package. In this article, we will discuss how to sort a slice in Golang. Sorting a slice in Go is simple, and there are several ways to accomplish it. The most common way is to use the sort.Slice() function, which sorts a slice using a provided comparison function. Here's how it works − Example package main import ( "fmt" "sort" ) func main() ...

In Golang, a slice is a dynamically-sized array that can store a collection of elements of the same type. Sometimes, you may need to remove duplicate values from a slice to ensure that each element in the slice is unique. In this article, we'll discuss how to remove duplicate values from a slice in Golang. Method 1: Using a Map One way to remove duplicate values from a slice in Golang is to use a map. Maps are a built-in type in Golang that allow you to store key-value pairs. We can use a map to keep track of the ... Read More
Go is a programming language that is well-suited for building high-performance, concurrent applications. One of the essential features of any application is the ability to work with date and time. In this article, we will explore how to print specific date-time in Go using the time package. Using the Time Package in Go The time package in Go provides a variety of functions for working with dates, times, and durations. The time.Time type represents a specific moment in time, and we can use its methods to format dates and times according to a specific layout. To print a specific date-time ... Read More
In Swift, you can extract regex matches using the NSRegularExpression class provided by the Foundation framework. Swift's NSRegularExpression is a powerful tool for working with regular expressions in Swift. It can be used for a wide range of text-processing tasks. NSRegularExpression Class You can make use of regular expressions with the Swift Foundation framework class called NSRegularExpression. With the help of regular expressions, you may search and replace text as well as create patterns that define collections of strings. You can use NSRegularExpression to convert a string pattern into a regular expression object, which you can then use to find ... Read More
