JSON has grown in popularity as a data format for transferring data across apps in recent years. JSON (JavaScript Object Notation) is a compact and simple-to-understand standard for exchanging data. It is widely used in server-to-server communication, mobile applications, and web applications. Its simplicity, concurrency, and scalability make GoLang a powerful programming language. The fundamentals of JSON with GoLang will be covered in this post. What is JSON? JSON is a simple, lightweight data exchange format that is simple for both people and robots to comprehend and generate. It is a completely language-independent text format that adheres to principles that ... Read More

The base64 package in Golang provides several functions for encoding and decoding binary data in base64 format. DecodeString(), one of the most often used functions, decodes a base64-encoded string and returns the original binary data. We will thoroughly examine the DecodeString() method and discover how to decode base64-encoded data in Golang. We'll start by talking about the function's fundamental syntax and parameters before looking at some real-world applications. You ought to be able to utilise the DecodeString() function in your own Golang projects after reading this article. Basic Syntax of base64.DecodeString() The basic syntax of the DecodeString() function is as ... Read More

Base64 package in Golang is a standard library package that offers capabilities for base64-encoding and -decoding binary data. Base64 is a popular method of encoding that enables binary data to be represented using just sharable ASCII letters, making it perfect for transmission over text-based protocols like HTTP and SMTP. We'll look into the Golang base64 package and discover how to encrypt and decrypt data in base64 format using the package's functions. We'll also talk about the best ways to interact with binary data in Golang and examine some typical use cases for base64 encoding and decoding. You ought to be ... Read More

Let's look at how ‘gofmt’ can automatically style your Go source code in a consistent manner so that it is easier to understand and manage. In order to write readable, maintainable code, it must be formatted correctly. Go source code can be formatted using the 'gofmt' command-line tool. Using a set of rules and conventions, this programme automatically reformats your Go code to make it simpler to read and comprehend. What is Gofmt? A command-line tool called Gofmt is used to format Go source code consistently. Your code's space, indentation, and line breaks are automatically adjusted to make it easier ... Read More

Atomic Variable in Golang offer an alternative to use locks or other synchronisation primitives to execute atomic operations on shared variables. When programming concurrently, synchronisation and mutual exclusion are essential to ensuring that threads or processes can access shared resources without interfering with one another. The fast and scalable synchronisation and coordination of concurrent access to shared variables is made possible by the use of atomic variables. What is an Atomic Variable? An atomic variable is a shared variable that may be read from and written to simultaneously by several goroutines while still ensuring that all actions are atomic. The ... Read More

Anonymous structures and fields in Golang are a powerful feature that can be used to simplify and improve the readability of your code. These constructs allow you to define new data types on the fly without having to create a new named struct. Let's examine anonymous fields and structures in Go in more detail. What is an Anonymous Structure? In Go, a structure is a collection of fields that can be used to define a new data type. Normally, you would define a named structure like this − type Person struct { Name string ... Read More

Inversion count is a step counting method by which we can calculate the number of sorting steps taken by a particular array. It is also capable to count the operation time span for an array. But, if we want to sort an array in a reverse manner, the count will be maximum number present in that array. Array: { 5, 4, 3, 2, 1} // for the reverse manner Pairs: {5, 4}, {5, 3} , {3, 2}, {3, 1}, {2, 1}, {4, 3}, {4, 2}, {4, 1}, }, {5, 2}, {5, 1} Output: 10 Array: {1, 2, 3, 4, ... Read More

This tutorial will help us to creat a haskell program that can covert a given hexadecimal number to a decimal number using revers, map and fold1 functions Hexadecimal to decimal conversion is the process of converting a number from the hexadecimal number system to the decimal number system. The hexadecimal number system uses a base of 16, which means that there are 16 unique symbols used to represent numbers in this system (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F). The decimal number system, on the other hand, uses a base of ... Read More

We can convert the Decimal number to an Octal using the recursion and unfoldr function of Haskell. Decimal to octal conversion is a process of converting a decimal (base-10) number to its equivalent representation in octal (base-8) numbering system. In decimal numbering system, we use 10 digits (0 to 9) to represent a number. In octal numbering system, we use 8 digits (0 to 7) to represent a number. To convert a decimal number to its equivalent octal representation, we divide the decimal number by 8 repeatedly until the quotient becomes 0, and keep track of the remainders. The remainders, ...

We can create a half-diamond star pattern in Haskell using recursive and replicate functions. The half-diamond star pattern is a pattern made up of asterisks (*) arranged in the shape of a half-diamond. It is typically created by printing a series of asterisks in a pyramid shape, starting with a single asterisk in the first row, two asterisks in the second row, and so on, until the middle row which contains the maximum number of asterisks. From that row onwards, the number of asterisks decreases until there is only a single asterisk in the last row. Algorithm Step 1 ... Read More
