Lab 2: Three Challenges from Hackerank Evan Misshula <2018-09-27 Thu> Hackerank HackerRank is a technology company[1] that focuses on competitive programming challenges for both consumers and businesses, where develop- ers compete by trying to program according to provided specifications.[2][3] HackerRank’s programming challenges can be solved in a variety of programming languages (including Java, C++, PHP, Python, SQL, JavaScript) and span multiple computer science domains.[4] On the consumer side, when a programmer submits a solution to a programming challenge, their submission is scored on the accuracy of their out- put. Programmers are then ranked globally on the HackerRank leaderboard and earn badges based on their accomplishments to drive competition among users. In addition to individual programming challenges, HackerRank also hosts contests (often referred to by HackerRank as "CodeSprints") where users compete on the same programming challenges during a set period of time and are then ranked at the conclusion of the event. HackerRank is part of the growing gamification trend within competitive computer programming[5] and the consumer-side of their website is free for coders to use. Step 1 Create a free hackerrank account. https://www.hackerrank.com/dashboard Step 2 Look at the Functionial programming challenges on Hackerank. https:// www.hackerrank.com/domains/fp?filters%5Bstatus%5D%5B%5D=unsolved 1 Step 3 Select and solve three problems from the functional programming challenges Step four Take a screen shot of the Congratulations screen to show that it passed the test. Step 5 Attach the solutions as three separate .hs files Step 6 create a lab document 1. Your lab must be a document PDF, docx and ODS formats are ac- ceptable 2.

A Flipped Classroom Approach for Teaching a Master's Course on Artificial Intelligence
A Flipped Classroom Approach for Teaching a Master’s Course on Artificial Intelligence Robin T. Bye? Software and Intelligent Control Engineering Laboratory Department of ICT and Natural Sciences Faculty of Information Technology and Electrical Engineering NTNU — Norwegian University of Science and Technology Postboks 1517, NO-6025 Ålesund, Norway Email: [email protected] Website: http://www.robinbye.com Abstract. In this paper, I present a flipped classroom approach for teaching a master’s course on artificial intelligence. Traditional lectures from the classroom are outsourced to an open online course that con- tains high quality video lectures, step-by-step tutorials and demonstra- tions of intelligent algorithms, and self-tests, quizzes, and multiple-choice questions. Moreover, selected problems, or coding challenges, are cherry- picked from a suitable game-like coding development platform that rids both students and the teacher of having to implement much of the fun- damental boilerplate code required to generate a suitable simulation en- vironment in which students can implement and test their algorithms. Using the resources of the online course and the coding platform thus free up much valuable time for active learning in the classroom. These learning activities are carefully chosen to align with the intended learn- ing outcomes, curriculum, and assessment to allow for learning to be constructed by the students themselves under guidance by the teacher. Thus, I perceive the teacher’s role as a facilitator for learning, much similar to that of a personal trainer or a coach. Emphasising problem- solving as key to achieving intended learning outcomes, the aim is to select problems that strike a balance between detailed step-by-step tuto- rials and highly open-ended problems.

Developer Skills Report Research.Hackerrank.Com Intro
2019 Developer Skills Report research.hackerrank.com Intro Programming is like art—both the process of writing code and the code in itself. Converting an idea that only existed in your head into reality is an unparalleled feeling. It’s a kind of mindfulness that keeps you in a state of flow when you love the work you do. And, when your product impacts millions of developers and helps them find the right place to work—it’s both exciting and scary! At HackerRank we have had the opportunity to build a product that’s used by a community of more than 5 million developers (more than 20% of the world’s developer population) and more than 1,200 customers to match every developer to the right job based on skill. The underlying infrastructure of the hiring process is going through a dramatic shift. Candidates are now being evaluated based on their skills and not their pedigree. This opens up a lot more opportunities for developers and smart companies worldwide are recognizing this and making the shift. We surveyed our community with questions ranging from which technology they find the most promising to what they look for in a job and during the interview process. More than 70,000 developers participated in the survey (that’s right!) and enclosed is a treasure trove of insight on what’s happening in the land of developers. Enjoy the report and as always feel free to tweet @hackerrank or email us [email protected] your comments. Let’s build an even playing field!

Puzzleme: Leveraging Peer Assessment for In-Class Programming Exercises
PuzzleMe: Leveraging Peer Assessment for In-Class Programming Exercises APRIL YI WANG∗, University of Michigan, USA YAN CHEN∗, University of Michigan, USA JOHN JOON YOUNG CHUNG, University of Michigan, USA CHRISTOPHER BROOKS, University of Michigan, USA STEVE ONEY, University of Michigan, USA Peer assessment, as a form of collaborative learning, can engage students in active learning and improve their learning gains. However, current teaching platforms and programming environments provide little support to integrate peer assessment for in-class programming exercises. We identified challenges in conducting such exercises and adopting peer assessment through formative interviews with instructors of introductory programming courses. To address these challenges, we introduce PuzzleMe, a tool to help Computer Science instructors to conduct engaging in-class programming exercises. PuzzleMe leverages peer assessment to support a collaboration model where students provide timely feedback on their peers’ work. We propose two assessment techniques tailored to in-class programming exercises: live peer testing and live peer code review. Live peer testing can improve students’ code robustness by allowing them to create and share lightweight tests with peers. Live peer code review can improve code understanding by intelligently grouping students to maximize meaningful code reviews. A two-week deployment study revealed that PuzzleMe encourages students to write useful test cases, identify code problems, correct misunderstandings, and learn a diverse set of problem-solving approaches from peers. CCS Concepts: • Computer systems organization ! Embedded systems; Redundancy; Robotics; • Net- works ! Network reliability. Additional Key Words and Phrases: peer assessment, live programming, synchronous code sharing ACM Reference Format: April Yi Wang, Yan Chen, John Joon Young Chung, Christopher Brooks, and Steve Oney.
