Wolfgang, Paul A. Preface Our goal in writing this book was to combine a strong emphasis on problem solving and software design with the study of data structures. To this end, we discuss applications of each data structure to motivate its study. After providing the specification interface and the implementation a Java class , we then cover case studies that use the data structure to solve a significant problem. Examples include maintaining an ordered list, evaluating arithmetic expressions using a stack, finding the shortest path through a maze, and Huffman coding using a binary tree and a priority queue.

We also provide a performance analysis when appropriate. Readers gain an understanding of why different data structures are needed, the applications they are suited for, and the advantages and disadvantages of their possible implementations.

Intended Audience This book was written for anyone with a curiosity or need to know about data structures, those essential elements of good programs and reliable software. We hope that the text will be useful to readers with either professional or educational interests. Although we expect that most read- ers will have completed a first programming course in Java, there is an extensive review chapter included as an appendix for those who may have taken a first programming course in a different language, or for those who need a refresher in Java.

We begin the study of a new data structure by specifying an abstract data type as an interface, which we adapt from the Java API. Readers are encouraged throughout the text to use the Java Collections Framework as a resource for their programming. Our expectation is that readers who complete this book will be familiar with the data struc- tures available in the Java Collections Framework and will be able to use them in their future programming. However, we also expect that they will want to know how the data structures are implemented, so we provide thorough discussions of classes that implement these data structures.

Each class follows the approach taken by the Java designers where appropriate. There is also coverage of exceptions and exception handling. Features of the Third Edition We had two major goals for the third edition. The first was to bring the coverage of Java up to Java 8 by introducing new features of Java where appropriate. For example, we use the Java 7 diamond operator when creating new Collection objects. Using these features significantly improved the code.

The second major goal was to provide additional emphasis on testing and debugging. A third goal was to ease the transition to Java for Python programmers. When introducing Java data structures for example, arrays, lists, sets, and maps , we compared them to equiva- lent Python data structures.

We also combined the chapters on stacks and queues and increased our emphasis on using Deque as an alternative to the legacy Stack class. We also added a discussion of Timsort, which is used in Java 8, to the chapter on sorting algorithms. Finally, some large case studies and an appendix were moved to online supplements. Case Studies We illustrate OOD principles in the design and implementation of new data structures and in the solution of approximately 20 case studies. As is done in industry, we sometimes perform these steps in an iterative fashion rather than in strict sequence.

Several case studies have extensive discussions of testing and include methods that automate the test- ing process. Some case studies are revisited in later chapters, and solutions involving different data structures are compared. We also provide additional case studies on the Web site for the textbook www. Although labeled an Appendix, the review chapter provides full coverage of the background topics and has all the pedagogical features discussed below of the other chapters. We expect most readers will have some experience with Java programming, but someone who knows another programming language should be able to undertake the book after careful study of the review chapter.

Pedagogy The book contains the following pedagogical features to assist inexperienced programmers in learning the material. Programming Style boxes discuss program features that illustrate good programming style and provide tips for writing clear and effective code.

Rather than provide several paragraphs of. We feel this will give readers an appreciation of the performance of various algorithms and methods and the process one follows to determine algorithm efficiency without bogging them down in unnecessary detail. The Exception class hierarchy is studied as an example of a Java class hierarchy. Each new data structure is introduced as an abstract data type ADT.

We pro- vide a specification of each ADT in the form of a Java interface. Next, we implement the data structure as a class that implements the interface. Finally, we study applications of the data structure by solving sample problems and case studies.

It also discuses using a debugger to help find and correct errors. Several applications of these data structures are provided. This chapter could be studied earlier. There is an optional section on list processing applications of recursion that may be skipped if the chapter is covered earlier.

It also shows how Java 8 lambda expressions and functional interfaces sup- port functional programming. It also discusses hashing and hash tables and shows how a hash table can be used in an implementation of these interfaces. Building an index for a file and Huffman Tree encoding and decoding are two case studies covered in this chapter. In most pro- grams, the last few chapters would be covered in a second course in algorithms and data structures. Items marked for students are accessi- ble on the Student Companion Web Site at the same address.

Acknowledgments Many individuals helped us with the preparation of this book and improved it greatly. We are grateful to all of them. We would like to thank Rolf Lakaemper and James Korsh, colleagues at Temple University, who used earlier editions in their classes. We would also like to thank a former Temple student, Michael Mayle, who provided preliminary solutions to many of the exercises.

Some of the testing methodologies discussed at the workshop were integrated into the chapter on Testing and Debugging. We are especially grateful to our reviewers who provided invaluable comments that helped us correct errors in each version and helped us set our revision goals for the next version. The individuals who reviewed this book are listed below. Although all the reviewers provided invaluable suggestions, we do want to give special thanks to Chris Ingram who reviewed every version of the first edition of the manuscript, including the preliminary pages for the book.

His care, attention to detail, and dedication helped us improve this book in many ways, and we are very grateful for his efforts. Besides the principal reviewers, there were a number of faculty members who reviewed sample pages of the first edition online and made valuable comments and criticisms of its content.

We would like to thank those individuals, listed below. They reviewed the preface, table of contents, and sample chapters and also provided valuable input on the book and future directions of the course. We would like to acknowledge the help and support of our colleague Frank Friedman who also read an early draft of this textbook and offered suggestions for improvement. Frank and Elliot began writing textbooks together many years ago and Frank has had substantial influ- ence on the format and content of these books.

Paul is grateful for his continued support. Finally, we would like to thank our wives who provided us with comfort and support through this arduous process. We very much appreciate their understanding and their sacrifices that enabled us to focus on this book, often during time we would normally be spending with them. In particular, Elliot Koffman would like to thank. D35K58 Printed in the United States of America 10 9 8 7 6 5 4 3 2 1 Koffman-ffirs. Pitfall boxes help readers identify common problems and how to avoid them.

Abstract data type

We discuss its use for such courses in more detail later in this pre face. This book is related to the following hooks:. Goodrich, R. Tamassia, and D. Goodrich and R. The design and analysis of efficient data structures has long been recognized as a vital subject in computing, for the study of data structures is part of the core of every coliegiate computer science and computer engineering major program we are familiar with. Elementary data structures are often briefly introduced in the first programming course or in an introduetion to computer science course and this is foliowed by a more in-depth introduetion to data structures in the courses that follow after this.

The move to event driven programming and then to object oriented programming presented major conceptual hurdles to my. Design, implement, test, and debug simple programs in an object-oriented programming. An object is a representation of a "thing" someone or something , and this representation is expressed with the help of a programming language. Comprehensive Version -Liang 2. Procedural programming is about writing procedures or methods that perform operations on the data, while object-oriented programming is about creating objects that contain both data and methods.

In computer science , an abstract data type ADT is a mathematical model for data types. An abstract data type is defined by its behavior semantics from the point of view of a user , of the data, specifically in terms of possible values, possible operations on data of this type, and the behavior of these operations. This mathematical model contrasts with data structures , which are concrete representations of data, and are the point of view of an implementer, not a user.

Abstract Data type ADT is a type or class for objects whose behaviour is defined by a set of value and a set of operations. The definition of ADT only mentions what operations are to be performed but not how these operations will be implemented. It does not specify how data will be organized in memory and what algorithms will be used for implementing the operations. The process of providing only the essentials and hiding the details is known as abstraction. The user of data type does not need to know how that data type is implemented, for example, we have been using Primitive values like int, float, char data types only with the knowledge that these data type can operate and be performed on without any idea of how they are implemented.

Три месяца назад до Фонтейна дошли слухи о том, что от Стратмора уходит жена. Он узнал также и о том, что его заместитель просиживает на службе до глубокой ночи и может не выдержать такого напряжения. Несмотря на разногласия со Стратмором по многим вопросам, Фонтейн всегда очень высоко его ценил. Стратмор был блестящим специалистом, возможно, лучшим в агентстве. И в то же время после провала с Попрыгунчиком Стратмор испытывал колоссальный стресс. Это беспокоило Фонтейна: к коммандеру сходится множество нитей в агентстве, а директору нужно оберегать свое ведомство. Фонтейну нужен был кто-то способный наблюдать за Стратмором, следить, чтобы он не потерял почву под ногами и оставался абсолютно надежным, но это было не так-то .

 Кто тебе это сказал? - спросил он, и в его голосе впервые послышались металлические нотки. - Прочитал, - сказал Хейл самодовольно, стараясь извлечь как можно больше выгоды из этой ситуации.  - В одном из ваших мозговых штурмов. - Это невозможно.

 Ах ты, пакостник. - Не знаю, что ты такое подумала. - Я рада, что поймала тебя, - продолжала.  - Мне нужен совет.

Сьюзан дошла до последней строки. В ней говорилось о том, к чему она совершенно не была готова. Последние слова записки стали для нее сильнейшим ударом.

Я вчера говорил с. Велел ему сегодня не приходить.

 - В глазах его читалась печаль.  - То, что сейчас скажу, я не собирался говорить никому. Она почувствовала, как по спине у нее пробежал холодок.

До сих пор Дэвиду Беккеру необыкновенно везло, и не следует и дальше искушать судьбу. Пиджак защитного цвета от него отделяли теперь уже только десять человек. Беккер шел, низко опустив голову. Халохот прокручивал в голове дальнейшие события. Все было очень просто: подойдя к жертве вплотную, нужно низко держать револьвер, чтобы никто не заметил, сделать два выстрела в спину, Беккер начнет падать, Халохот подхватит его и оттащит к скамье, как друга, которому вдруг стало плохо.

Сомнений в том, кого именно обвиняет Чатрукьян, не. Единственный терминал в шифровалке, с которого разрешалось обходить фильтры Сквозь строй, принадлежал Стратмору. Когда коммандер заговорил, в его голосе звучали ледяные нотки: - Мистер Чатрукьян, я не хочу сказать, что вас это не касается, но фильтры обошел.  - Очевидно, что Стратмор с трудом сдерживает гнев.  - Я уже раньше объяснял вам, что занят диагностикой особого рода.

Этот фонд, всемирная коалиция пользователей компьютеров, развернул мощное движение в защиту гражданских свобод, прежде всего свободы слова в Интернете, разъясняя людям реальности и опасности жизни в электронном мире. Фонд постоянно выступал против того, что именовалось им оруэлловскими средствами подслушивания, имеющимися в распоряжении правительственных агентств, прежде всего АНБ. Этот фонд был для Стратмора постоянной головной болью.

Взбираясь по решетчатым ступенькам, Сьюзан смотрела на массивную дубовую дверь кабинета, украшенную эмблемой АНБ, на которой был изображен могучий орел, терзающий когтями старинную отмычку. За этой дверью находился один из самых великих людей, которых ей довелось знать. Пятидесятишестилетний коммандер Стратмор, заместитель оперативного директора АНБ, был для нее почти как отец. Именно он принимал ее на работу, именно он сделал АНБ для нее родным домом. Когда десять лет назад Сьюзан поступила в агентство, Стратмор возглавлял Отдел развития криптографии, являвшийся тренировочной площадкой для новых криптографов, криптографов мужского пола.

Стратмор покачал головой: - Больше никто не знает о существовании кольца. Именно поэтому я и послал за ним Дэвида. Я хотел, чтобы никто ничего не заподозрил. Любопытным шпикам не придет в голову сесть на хвост преподавателю испанского языка. - Он профессор, - поправила его Сьюзан и тут же пожалела об .

Посмотри. Бринкерхофф растерянно постоял минутку, затем подбежал к окну и встал рядом с Мидж. Та показала ему последние строчки текста. Бринкерхофф читал, не веря своим глазам.
