Master the concise and expressive power of a pragmatic multi-paradigm language for JVM, Android and beyond Key Featuresa- Language fundamentalsa- Object-oriented and functional programming with Kotlina- Kotlin standard librarya- Building domain-specific languagesa- Using Kotlin for Web developmenta- Kotlin for Android platforma- Coroutine-based concurrencyDescriptionThe purpose of this book is to guide a reader through the capabilities of the Kotlin language and give examples of using it for development of various applications be it desktop, mobile or Web. Although our primary focus is on the JVM and Android, the knowledge we're sharing here to various extents applies to other Kotlin-supported platforms such as JavaScript, native and even multi-platform applications.The book starts with an introduction to language and its ecosystem that will give you an understanding of the key ideas behind Kotlin design, introduce you to the Kotlin tooling and present you the basic language syntax and constructs. In the next chapters we'll get to know the multi-paradigm nature of Kotlin which allows you to create powerful abstractions by combining various aspects of functional and object-oriented programming. We'll talk about using common Kotlin APIs such as the standard library, reflection, and coroutine-based concurrency as well as the means for creating your own flexible APIs based on domain-specific languages. In the concluding chapters, we'll give examples of using Kotlin for more specialized tasks such as testing, building Android applications, Web development and creating microservices.What will you learnBy the end of the book, you'll obtain a thorough knowledge of all basic aspects of Kotlin programming. You'll be able to create a flexible and reusable code by taking advantage of object-oriented and functional features, use Kotlin standard library, compose your own domain-specific languages, write asynchronous code using Kotlin coroutines library as well. You'll also have a basic understanding of using Kotlin for writing test code, web applications and Android development. This knowledge will also give you a solid foundation for deeper learning of related development platforms, tools and frameworks.Who this book is forThe book is primarily aimed at developers familiar with Java and JVM and willing to get a firm understanding of Kotlin while having little to no experience in that language. Discussion of various language features will be accompanied, if deemed necessary, by comparisons with their Java's analogs which should simplify Java-to-Kotlin transition. Most of the material, however, is rather Java-agnostic and should be beneficial even without prior Java knowledge. In general, experience in object-oriented or functional paradigm is a plus, but not required.Table of Contents10. Annotations and Reflection11. Domain-Specific Languages12. Java Interoperability13.

How should I prepare for a Digital VLSI Verification Interview? What all topics do I need to know before I turn up for an interview? What all concepts do I need to brush up? What all resources do I have at my disposal for preparation? What does an Interviewer expect in an Interview? These are few questions almost all individuals ponder upon before an interview. If you have these questions in your mind, your search ends here as keeping these questions in their minds, authors have written this book that will act as a golden reference for candidates preparing for Digital VLSI Verification Interviews. Aim of this book is to enable the readers practice and grasp important concepts that are applicable to Digital VLSI Verification domain (and Interviews) through Question and Answer approach. To achieve this aim, authors have not restricted themselves just to the answer. While answering the questions in this book, authors have taken utmost care to explain underlying fundamentals and concepts. This book consists of 500+ questions covering wide range of topics that test fundamental concepts through problem statements (a common interview practice which the authors have seen over last several years). These questions and problem statements are spread across nine chapters and each chapter consists of questions to help readers brush-up, test, and hone fundamental concepts that form basis of Digital VLSI Verification. The scope of this book however, goes beyond technical concepts. Behavioral skills also form a critical part of working culture of any company. Hence, this book consists of a section that lists down behavioral interview questions as well. Topics covered in this book:1. Digital Logic Design (Number Systems, Gates, Combinational, Sequential Circuits, State Machines, and other Design problems)2. Computer Architecture (Processor Architecture, Caches, Memory Systems)3. Programming (Basics, OOP, UNIX/Linux, C/C++, Perl)4. Hardware Description Languages (Verilog, SystemVerilog)5. Fundamentals of Verification (Verification Basics, Strategies, and Thinking problems)6. Verification Methodologies (UVM, Formal, Power, Clocking, Coverage, Assertions)7. Version Control Systems (CVS, GIT, SVN)8. Logical Reasoning/Puzzles (Related to Digital Logic, General Reasoning, Lateral Thinking)9. Non Technical and Behavioral Questions (Most commonly asked)In addition to technical and behavioral part, this book touches upon a typical interview process and gives a glimpse of latest interview trends. It also lists some general tips and Best-Known-Methods to enable the readers follow correct preparation approach from day-1 of their preparations. Knowing what an Interviewer looks for in an interviewee is always an icing on the cake as it helps a person prepare accordingly. Hence, authors of this book spoke to few leaders in the semiconductor industry and asked their personal views on "What do they look for while Interviewing candidates and how do they usually arrive at a decision if a candidate should be hired?". These leaders have been working in the industry from many-many years now and they have interviewed lots of candidates over past several years. Hear directly from these leaders as to what they look for in candidates before hiring them. Enjoy reading this book. Authors are open to your feedback.

There are many distinct pleasures associated with computer programming. Craftsmanship has its quiet rewards, the satisfaction that comes from building a useful object and making it work. Excitement arrives with the flash of insight that cracks a previously intractable problem. The spiritual quest for elegance can turn the hacker into an artist. There are pleasures in parsimony, in squeezing the last drop of performance out of clever algorithms and tight coding. The games, puzzles, and challenges of problems from international programming competitions are a great way to experience these pleasures while improving your algorithmic and coding skills. This book contains over 100 problems that have appeared in previous programming contests, along with discussions of the theory and ideas necessary to attack them. Instant onlinegrading for all of these problems is available from two WWW robot judging sites. Combining this book with a judge gives an exciting new way to challenge and improve your programming skills. This book can be used for self-study, for teaching innovative courses in algorithms and programming, and in training for international competition. The problems in this book have been selected from over 1,000 programming problems at the Universidad de Valladolid online judge. The judge has ruled on well over one million submissions from 27,000 registered users around the world to date. We have taken only the best of the best, the most fun, exciting, and interesting problems available.

If you’re a student studying computer science or a software developer preparing for technical interviews, this practical book will help you learn and review some of the most important ideas in software engineering—data structures and algorithms—in a way that’s clearer, more concise, and more engaging than other materials. By emphasizing practical knowledge and skills over theory, author Allen Downey shows you how to use data structures to implement efficient algorithms, and then analyze and measure their performance. You’ll explore the important classes in the Java collections framework (JCF), how they’re implemented, and how they’re expected to perform. Each chapter presents hands-on exercises supported by test code online. Use data structures such as lists and maps, and understand how they work Build an application that reads Wikipedia pages, parses the contents, and navigates the resulting data tree Analyze code to predict how fast it will run and how much memory it will require Write classes that implement the Map interface, using a hash table and binary search tree Build a simple web search engine with a crawler, an indexer that stores web page contents, and a retriever that returns user query results Other books by Allen Downey include Think Java, Think Python, Think Stats, and Think Bayes.
