In Golang, the recovery mechanism provides a way to deal with panic and recover from it. Panic is an unexpected error that can cause the program to terminate. In this article, we are going to discuss what is recovered in golang. Here we are going to use two different methods: using handlePanic as well as the main() function along with examples to elaborate the concept. Syntax recover() In this Syntax, The handlePanic function is used in Go to recover from panics. It checks if a panic occurred using the recover() function, which returns the value passed to panic(). If ... Read More

In Go, race conditions occur when goroutines simultaneously read and write to the same shared memory space without synchronization mechanisms. This can cause data corruption, inconsistent states, or crashes.In this article, we are going to discuss race conditions in golang. Here we are going to use two different methods: Synchronization with WaitGroup as well as Synchronization with Mutex along with examples to elaborate the concept. Syntax sync.mutex() it is used to create a new mutex variable. The sync.Mutex type provides a way to control access to shared resources by acquiring and releasing locks mutex.Lock() This method is ... Read More

In this article we are going to discuss an overview of Benchmark testing. Benchmark testing is a basic portion of program optimization to grade the execution and productivity of code. In Golang, benchmark testing is backed through the built-in testing bundle. Here we are going to use the Benchmark function along with examples to elaborate on the concept. Syntax time.duration() This function is used to represent the time interval in go language. It allows the user to work with time durations. time.sleep() We use this function to stop the execution of a go language program for a specific ... Read More

The purpose of this interface is to provide a contract for implementing cache functionality in various data structures or systems. The Set method is responsible for storing a value in the cache with a specified key, while the Get method retrieves the value associated with a given key from the cache. In this article, we will create an interface called Cache that defines two methods: Set and Get. Here we are going to use two different methods − Get(key string) interface{} as well as Set(key string, value interface{}) along with examples to elaborate the concept. Syntax Set(key string, value interface{}) ... Read More

Radix sort is a non-comparative sorting algorithm that works by distributing elements into different buckets based on their significant digits. In this article, we will explore a Golang program that implements radix sort for sorting integers in descending order. Here we are going to use three different methods: Getmax, countsort, and radixsort along with examples to elaborate the concept. Syntax func getMax(arr []int) int The Syntax "func getMax(arr []int) int" defines a function named "getMax" that takes a slice of integers as a parameter and returns an integer value. func countSort(arr []int, exp int) The Syntax "func countSort(arr ...

A binary heap is a specialized tree-based data structure that satisfies the heap property, where the key of each node is either greater than or equal to (in a max heap) or less than or equal to (in a min heap) the keys of its children. In this program, we utilize a linked list to represent the binary heap. In this article, we will learn how to develop the Golang program to implement a binary heap using a linked list. Here we are going to use four different methods singly linked list, doubly linked list, custom node struct, and slice-based ... Read More

Red Black Tree is a self-balancing binary search tree with additional properties that ensure a balanced tree structure and efficient operations. The delete operation in a Red Black Tree involves rearranging the tree and maintaining the Red Black Tree properties after removing a node. Here we are going to use three different methods:deleteNode method, delete method, and successor transplant method along with examples to elaborate the concept. In this article, The Golang program implements the deletion operation in a Red Black Tree data structure using Golang. Syntax func (t *RedBlackTree) Delete(key int) The Syntax "func (t *RedBlackTree) Delete(key int)" ... Read More

Go and Erlang are two popular programming languages that are frequently utilized for building large-scale, conveyed, and fault-tolerant frameworks. Whereas both languages have their claims and various kinds of highlights and qualities, both share a common objective of giving designers effective devices for building versatile and adaptable frameworks. In this article, we'll compare Go and Erlang in terms of their concurrency models, fault-tolerance highlights, syntax, performance, and community support. By understanding the qualities and shortcomings of these two languages, developers can make educated choices approximately as to which language to utilize for their next project. Go Go is outlined for ... Read More

In this article we are going to create an interface named mailer that defines a send method using interfaces embedding as well as Function as parameter. Interface in go language is a collection of methods that define a set of behavior. Algorithm Create a Mailer interface with a Send function that accepts two parameters: the recipient's email address and the email body. If an error occurs during the sending procedure, the Send method should return an error. Example 1 Make structs that represent various mailer implementations, such as SmtpMailer, SendGridMailer, and so on. ... Read More

In this Golang article we will learn to create an interface named writer that defines a write method write method for file type as well as writer interface and filet type. Syntax data := []byte("Hello, World!") It is used to declare a byte slice in go language. data : it is a variable declaration for a var named data. []byte: the type of variable “data” as a byte slice. ... Read More
