Git vs GitHub [Differences Explained]

Introduction to Git and GitHub

Git and GitHub are widely used tools in the field of software development. While Git is a distributed version control system, GitHub is a web-based hosting service for Git repositories. In this comparison at OpenGenus, we will explore the features, applications, differences, and common questions related to Git and GitHub.

Primary and Auxiliary Constructors in Scala

A constructor is a special method that is used to initialize an object. Constructors are defined inside a class; with the same name as the class in JAVA but in Scala that is not the case. We use this keyword to initialize a constructor in Scala. There are 2 types of classes in Scala, primary constructor and auxiliary constructor. In Scala, we don't have to code getter and setter methods for primary constructors.

Adapter Design Pattern

The adapter pattern is a software design pattern (also known as wrapper, an alternative naming shared with the decorator pattern) that allows the interface of an existing class (in my implementation I call it Adaptee) to be used as another interface (I call it Target). It is often used to make existing classes work with others without modifying their source code. In this article at OpenGenus, we show two ways to implement the Adapter design pattern.

Winograd's Convolution Theorem [Explained]

Convolution itself is a very hefty process, in most cases there is a lot of repetitive informations from one step of the window to the next.

This significant overlap gives us the intuition that there maybe more efficient methods, that could omit extra calculations and give us a more efficient convolution method.

This theorem which gives us this efficient method has a more mathematical descent and did not originate in Convolutional netwroks. We saw our first CNN is 1994, while we had this theorem...

Next Greater Element using Stack

Table of contents:Problem statementBrute Force approachApproach using StackReal World examples.PROBLEM STATEMENT

Given an array of integers, arr, of length N. The task is to find the Next Greater Element (NGE) for each element in the array. We will solve this problem completely in this OpenGenus article.

For a given element arr[i], the Next Greater Element is the first element to the right of arr[i] that is greater than arr[i]. If there is no such element, the Next Greater Element for tha...

Basics of Scala Programming

Reading time: 18 minutes | Coding time: 22 minutes

Introduction

Scala, short for "Scalable Language," is a modern programming language that blends object-oriented and functional programming paradigms. It was designed to address the limitations and complexities of Java while offering a concise, expressive, and flexible syntax. Developed by Martin Odersky and his team, Scala was first released in 2003 and has since gained popularity in various domains including web development, data analysis, an...
