Golang program to create a module with constant
In the Go programming language, a module is a collection of packages and it helps to manage them and their dependencies. In this article, we will create a module with constant using two examples. In the first example, we will create a constant string that will be returned by the function and that function will be called from the main of another module. In the second example, a function will be created to return the string and print when called by the main of another module. Algorithm Import the required packages in the program Create a constant string in ...
Read MoreDifference between GO and Erlang
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 MoreGolang program to create filter for the Employees
Go Language allows you to apply a filter on particular data for analyzing specified data, work on a particular property of data, data integration and more.In this article we are going to write a program to create a filter for the employees, using iterative filtering, functional filtering, as well as using go language built in filtering function. Syntax filtered := funk.Filter(collection, func(item Type) bool {…}) collection = It is the original collection to filter. This function takes two arguments, a collection and a filtering function. Algorithm Make ...
Read MoreGolang Program to Create an Interface Named Mailer that Defines a Send Method
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 MoreGolang Program to Create an Interface Named Writer that Defines a Write Method
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 MoreGolang Program to Create Two Goroutines
When working with go language there may be instances where you need to create two goroutines for parallel processing, asynchronous operations and more. In this go language article we will explore how to create two goroutines using anonymous functions, named functions as well as using function calls.In golanguage a goroutine is an independent concurrent function, it enables concurrent programming by allowing the functions to run concurrently. Syntax time.Sleep(duration) It is a built-in go language function used to pause the execution of a program. It ...
Read MoreGolang Program to Creates a Unidirectional Sending Channel and Passes it to a Function that Returns a Unidirectional Receiving Channel
A unidirectional sending channel is used to send the values to the channel, while the unidirectional receiving channel is used to receive the data from the channel. These channels are used in concurrent data processing, data sharing and more. In this golang article we are going to create a program to create a unidirectional sending and pass it to a function that returns a unidirectional receiving channel using function parameters, type conversion as well as channel composition. Algorithm Define the sender Function that accepts a send-only channel named “ch” of type integer. ...
Read MoreGolang Program to Find Average Paid Employee
It is very important to know about the average salary paid to an employee in an organization for analysis, research and rewards. In this article we are going to find out the average employee salary in go language using iteration, reduce function as well as goroutines and channels. Algorithm CalculateAverage is a function that accepts a slice of float64 values salaries as input and returns a float64 value. Set the total to 0 and count the length of the salary slice. Using a ...
Read MoreGolang Program to Implement Kaden\'s Algorithm
There is a famous maximum sum subarray problem, in which we have a 1 Dimensional array and must find the maximum sum in that subarray. To solve this problem, the most naive approach will be to find all the sub − arrays, sum their elements, and return the maximum, but the time complexity will be O(N*N). To reduce this there is an algorithm that will reduce the time complexity from O(N*N) to O(N) named as Kadens Algorithm. In programming, there are algorithms based on the Dynamic programming concept in which the problem is broken into sub − problems and the ...
Read MoreGolang Program to Implement Binary Search Algorithm
In programming, to search for anything from an array, linked List, or any other data structures we have a few search algorithms, one of which is binary search. In binary search, the prerequisite is that the data should be sorted. In binary search, we follow the divide and conquer approach in which we divide the data by applying some conditions and then perform the operation on that data only. In this way, we reduce the time complexity. For example, if we have an array of elements {20, 44, 45, 54, 67, 88, 91} and we want to find 44 then ...
