| count binary substrings hackerrank solution: Guide to Competitive Programming Antti Laaksonen, 2018-01-02 This invaluable textbook presents a comprehensive introduction to modern competitive programming. The text highlights how competitive programming has proven to be an excellent way to learn algorithms, by encouraging the design of algorithms that actually work, stimulating the improvement of programming and debugging skills, and reinforcing the type of thinking required to solve problems in a competitive setting. The book contains many “folklore” algorithm design tricks that are known by experienced competitive programmers, yet which have previously only been formally discussed in online forums and blog posts. Topics and features: reviews the features of the C++ programming language, and describes how to create efficient algorithms that can quickly process large data sets; discusses sorting algorithms and binary search, and examines a selection of data structures of the C++ standard library; introduces the algorithm design technique of dynamic programming, and investigates elementary graph algorithms; covers such advanced algorithm design topics as bit-parallelism and amortized analysis, and presents a focus on efficiently processing array range queries; surveys specialized algorithms for trees, and discusses the mathematical topics that are relevant in competitive programming; examines advanced graph techniques, geometric algorithms, and string techniques; describes a selection of more advanced topics, including square root algorithms and dynamic programming optimization. This easy-to-follow guide is an ideal reference for all students wishing to learn algorithms, and practice for programming contests. Knowledge of the basics of programming is assumed, but previous background in algorithm design or programming contests is not necessary. Due to the broad range of topics covered at various levels of difficulty, this book is suitable for both beginners and more experienced readers. |

System design questions have become a standard part of the software engineering interview process. These interviews determine your ability to work with complex systems and the position and salary you will be offered by the interviewing company. Unfortunately, SDI is difficult for most engineers, partly because they lack experience developing large-scale systems and partly because SDIs are unstructured in nature. Even engineers who've some experience building such systems aren't comfortable with these interviews, mainly due to the open-ended nature of design problems that don't have a standard answer. This book is a comprehensive guide to master SDIs. It was created by hiring managers who have worked for Google, Facebook, Microsoft, and Amazon. The book contains a carefully chosen set of questions that have been repeatedly asked at top companies. What's inside? This book is divided into two parts.

| count binary substrings hackerrank solution: Coding Interviews Harry He, 2013-01-31 This book is about coding interview questions from software and Internet companies. It covers five key factors which determine performance of candidates: (1) the basics of programming languages, data structures and algorithms, (2) approaches to writing code with high quality, (3) tips to solve difficult problems, (4) methods to optimize code, (5) soft skills required in interviews. The basics of languages, algorithms and data structures are discussed as well as questions that explore how to write robust solutions after breaking down problems into manageable pieces. It also includes examples to focus on modeling and creative problem solving. Interview questions from the most popular companies in the IT industry are taken as examples to illustrate the five factors above. Besides solutions, it contains detailed analysis, how interviewers evaluate solutions, as well as why they like or dislike them. The author makes clever use of the fact that interviewees will have limited time to program meaningful solutions which in turn, limits the options an interviewer has. So the author covers those bases. Readers will improve their interview performance after reading this book. It will be beneficial for them even after they get offers, because its topics, such as approaches to analyzing difficult problems, writing robust code and optimizing, are all essential for high-performing coders. |

Since the publication of its first edition in 1984 and its second edition in 1996, Structure and Interpretation of Computer Programs (SICP) has influenced computer science curricula around the world. Widely adopted as a textbook, the book has its origins in a popular entry-level computer science course taught by Harold Abelson and Gerald Jay Sussman at MIT. SICP introduces the reader to central ideas of computation by establishing a series of mental models for computation. Earlier editions used the programming language Scheme in their program examples. This new version of the second edition has been adapted for JavaScript. The first three chapters of SICP cover programming concepts that are common to all modern high-level programming languages. Chapters four and five, which used Scheme to formulate language processors for Scheme, required significant revision. Chapter four offers new material, in particular an introduction to the notion of program parsing. The evaluator and compiler in chapter five introduce a subtle stack discipline to support return statements (a prominent feature of statement-oriented languages) without sacrificing tail recursion. The JavaScript programs included in the book run in any implementation of the language that complies with the ECMAScript 2020 specification, using the JavaScript package sicp provided by the MIT Press website. |

| count binary substrings hackerrank solution: Dynamic Programming for Coding Interviews Meenakshi, Kamal Rawat, 2017-01-18 I wanted to compute 80th term of the Fibonacci series. I wrote the rampant recursive function, int fib(int n){ return (1==n || 2==n) ? 1 : fib(n-1) + fib(n-2); } and waited for the result. I wait… and wait… and wait… With an 8GB RAM and an Intel i5 CPU, why is it taking so long? I terminated the process and tried computing the 40th term. It took about a second. I put a check and was shocked to find that the above recursive function was called 204,668,309 times while computing the 40th term. More than 200 million times? Is it reporting function calls or scam of some government? The Dynamic Programming solution computes 100th Fibonacci term in less than fraction of a second, with a single function call, taking linear time and constant extra memory. A recursive solution, usually, neither pass all test cases in a coding competition, nor does it impress the interviewer in an interview of company like Google, Microsoft, etc. The most difficult questions asked in competitions and interviews, are from dynamic programming. This book takes Dynamic Programming head-on. It first explain the concepts with simple examples and then deep dives into complex DP problems. |

| count binary substrings hackerrank solution: The C++ Programming Language Bjarne Stroustrup, 2013-07-10 The new C++11 standard allows programmers to express ideas more clearly, simply, and directly, and to write faster, more efficient code. Bjarne Stroustrup, the designer and original implementer of C++, has reorganized, extended, and completely rewritten his definitive reference and tutorial for programmers who want to use C++ most effectively. The C++ Programming Language, Fourth Edition, delivers meticulous, richly explained, and integrated coverage of the entire language—its facilities, abstraction mechanisms, standard libraries, and key design techniques. Throughout, Stroustrup presents concise, “pure C++11” examples, which have been carefully crafted to clarify both usage and program design. To promote deeper understanding, the author provides extensive cross-references, both within the book and to the ISO standard. New C++11 coverage includes Support for concurrency Regular expressions, resource management pointers, random numbers, and improved containers General and uniform initialization, simplified for-statements, move semantics, and Unicode support Lambdas, general constant expressions, control over class defaults, variadic templates, template aliases, and user-defined literals Compatibility issues Topics addressed in this comprehensive book include Basic facilities: type, object, scope, storage, computation fundamentals, and more Modularity, as supported by namespaces, source files, and exception handling C++ abstraction, including classes, class hierarchies, and templates in support of a synthesis of traditional programming, object-oriented programming, and generic programming Standard Library: containers, algorithms, iterators, utilities, strings, stream I/O, locales, numerics, and more The C++ basic memory model, in depth This fourth edition makes C++11 thoroughly accessible to programmers moving from C++98 or other languages, while introducing insights and techniques that even cutting-edge C++11 programmers will find indispensable. This book features an enhanced, layflat binding, which allows the book to stay open more easily when placed on a flat surface. This special binding method—noticeable by a small space inside the spine—also increases durability. |

An Article-by-Article Commentary Eckart Brödermann, 2023-05-12 The Unidroit Principles of International Commercial Contracts provide an excellent and practice proven tool for cross-border contracts: They constitute a neutral and pragmatic business oriented contractual regime for cross-border contracts They contain multiple solutions to typical contractual questions regarding the life of a contract, often by way of a compromise between civil and common law They have been referenced in hundreds of decisions of arbitral tribunals or national state courts They have been endorsed inter alia by the United Nations Commission on International Trade Law (last in 2021) and the Union Internationale des Avocats (2020) bringing together through its bar association and individual members approximately two million lawyers in more than 110 countries. Thirty years after their first publication, it is arguably malpractice to ignore them. In this fully revised and enlarged 2nd edition, the commentary continues to analyse the Unidroit Principles article by article from a practical perspective, while always discussing alternative courses of action, where they apply. The commentary includes proposals for choice of the Unidroit Principles’ clauses and practical guidance for their use as template, or to supplement the CISG or national law. In addition to arbitral and state court decisions and recent literature, the 2nd edition includes an in-depth analysis of extensive legislative material. The author is a German practitioner with international training and familiarity with both common and civil law. He has been admitted to the New York Bar and also teaches at the University of Hamburg as a Professor of Law. The author is using the Unidroit Principles for more than 20 years in his commercial and arbitration practice, in recent years on a daily basis in multiple industries. As he shares his experience under the Unidroit Principles, the commentary can also be used as a practical guide and checklist of issues to consider in international contracting. Die Unidroit Principles of International Commercial Contracts sind das ideale Instrument für grenzüberschreitende Verträge: sie bilden ein neutrales, pragmatisches und wirtschaftsorientiertes Regime für grenzüberschreitende Verträge sie enthalten zahlreiche praxisnahe Lösungen für übliche Vertragsfragen und versöhnen dabei Civil Law und Common Law Unidroit Principles werden in zahlreichen Entscheidungen von Schiedsgerichten oder nationalen Gerichten zitiert u.a. befürwortet von der Kommission der Vereinten Nationen für internationales Handelsrecht (zuletzt 2021) und der Union Internationale des Avocats (2020), die über ihre Anwaltskammern und Einzelmitglieder rund zwei Millionen Anwälte in mehr als 110 Ländern vereinen. Nach dreißig Jahren Anwendung in der Praxis kann es sich rächen, die Unidroit Principles zu ignorieren! Die vollständig überarbeiteten und erweiterte 2. Auflage des Kommentars analysiert weiterhin die Unidroit Principles, Artikel für Artikel, aus Sicht des Praktikers. Alternative Handlungsmöglichkeiten werden dort erörtert, wo sie sinnvoll und anwendbar sind. Der Kommentar enthält Vorschläge für die Wahl der Klauseln der Unidroit Principles und praktische Anleitungen für deren Verwendung, auch als Vorlage oder zur Ergänzung des CISG oder des nationalen Rechts. Neben Schiedsgerichts- und staatlichen Gerichtsentscheidungen sowie aktueller Literatur enthält die 2. Auflage eine eingehende Analyse des umfangreichen Gesetzesmaterials. Als deutscher Praktiker mit internationaler Ausbildung ist der Autor mit dem Common Law und dem Civil Law bestens vertraut. Er ist als Rechtsanwalt in New York zugelassen und lehrt als Professor für Rechtswissenschaften an der Universität Hamburg. Der Autor wendet die Unidroit Principles seit 20 Jahren in seiner täglichen Handels- und Schiedsgerichtspraxis an. Aufgrund zahlreicher Berichterstattung aus der Praxis bietet der Kommentar zugleich ein Handbuch und Checklisten zum allgemeinen Schuldrecht in grenzübergreifenden Fällen. |

| count binary substrings hackerrank solution: Problem Solving 101 Ken Watanabe, 2009-03-05 The fun and simple problem-solving guide that took Japan by storm Ken Watanabe originally wrote Problem Solving 101 for Japanese schoolchildren. His goal was to help shift the focus in Japanese education from memorization to critical thinking, by adapting some of the techniques he had learned as an elite McKinsey consultant. He was amazed to discover that adults were hungry for his fun and easy guide to problem solving and decision making. The book became a surprise Japanese bestseller, with more than 370,000 in print after six months. Now American businesspeople can also use it to master some powerful skills. Watanabe uses sample scenarios to illustrate his techniques, which include logic trees and matrixes. A rock band figures out how to drive up concert attendance. An aspiring animator budgets for a new computer purchase. Students decide which high school they will attend. Illustrated with diagrams and quirky drawings, the book is simple enough for a middleschooler to understand but sophisticated enough for business leaders to apply to their most challenging problems. |
