In Golang, trimming the right-hand side of a slice of bytes refers to removing a specific set of bytes from the end of the slice. This can be useful when working with byte slices that contain a specific suffix that needs to be removed before further processing. In this article, we will explore how to trim the right-hand side of a slice of bytes in Golang. Using the bytes.TrimSuffix() function The Golang bytes package provides a built-in function called TrimSuffix() that can be used to trim a suffix from a slice of bytes. This function takes two arguments: the byte ... Read More
There are two types loudspeakers namely, active speakers and passive speakers, used in music systems to produce sound output. The fundamental difference between active speakers and passive speakers is that active speakers consist of a built-in amplifier to produce amplified sound output, whereas passive speakers do not have built-in amplifier, instead they need an external amplifier to power the speakers. In this article, we will discuss all the important differences between active speakers and passive speakers. But before that let’s have a look into the basics of active and passive speakers individually. What is an Active Speaker? A type ... Read More
In Golang, trimming the left-hand side of a slice of bytes means removing the specified prefix from the beginning of the slice. Trimming can be useful when working with byte slices, where a specific prefix needs to be removed before further processing. In this article, we will explore how to trim the left-hand side of a slice of bytes in Golang. Using the bytes.TrimLeft() function Golang provides a built-in bytes package that contains many useful functions for working with byte slices. The bytes.TrimLeft() function can be used to trim a specific prefix from the beginning of a slice of bytes. ... Read More
A microcontroller is a small processing device which is primarily designed to perform specific functions within a large system. For example, a microcontroller is used in an air conditioner to automatically control and adjust the temperature of a room. The main parts that a microcontroller has are: central processing unit (CPU), memory unit, and I/O interfaces. All these components of the microcontroller are formed on a single chip. A microcontroller can be programmed using various programming languages like C language, assembly language, etc. to perform a specific function. Microcontrollers are widely used in a variety of electronic devices, such as ... Read More
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
