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...

Memory Game in Java

Memory games are popular brain-training exercises designed to challenge and improve our memory and cognitive abilities. These games typically involve matching pairs of identical items hidden among a set of cards or tiles, which are then shuffled and placed face down. Players must remember the position of each item and make matches by turning over two cards at a time. The objective is to find all the matching pairs by memorizing the location of the items in the shortest time and with the fewest a...

Training process of Deep Learning models

Abstract

Deep learning has revolutionized the field of artificial intelligence by enabling machines to learn and make decisions on their own, similar to the human brain. The training process of deep learning models is a crucial aspect of this technology, as it determines the model's ability to generalize and perform well on unseen data. In this article at OpenGenus, we will delve into the training process, explore key terms such as epoch and Adam optimizer, and briefly discuss how the process va...
