The study of data structures, a fundamental component of a computer science edu-cation, serves as the foundation upon which many other computer science fields are built. Some knowledge of data structures is a must for students who wish to do work in design, implementation, testing, or maintenance of virtually any software system.
This book highlights three important aspects of data structures. Second, data structures are presented in an object-oriented setting in accordance with the current design and implementation paradigm. In particular, the information-hiding principle to ad-vance encapsulation and decomposition is stressed. It is also useful and natural for introducing data structures. This book provides the material for an introductory data structures course, as well as for an advanced data structures and algorithms course.
Most chapters include a case study that illustrates a complete context in which certain algorithms and data structures can be used. These case studies were chosen from different areas of computer science such as interpreters, symbolic computation, and file processing, to indicate the wide range of applications to which topics under discussion may apply.
However, theoretical analysis is equally im-portant, so presentations of algorithms are integrated with analyses of efficiency. Great care is taken in the presentation of recursion because even advanced stu-dents have problems with it. Experience has shown that recursion can be explained best if the run-time stack is taken into consideration. Changes to the stack are shown when tracing a recursive function not only in the chapter on recursion, but also in other chapters.
For example, a surprisingly short function for tree traversal may re-main a mystery if work done by the system on the run-time stack is not included in the explanation. Standing aloof from the system and retaining only a purely theoreti-cal perspective when discussing data structures and algorithms are not necessarily helpful.
The thrust of this book is data structures, and other topics are treated here only as much as necessary to ensure a proper understanding of this subject. Algo-rithms are discussed from the perspective of data structures, so the reader will not find a comprehensive discussion of different kinds of algorithms and all the facets that a full presentation of algorithms requires.
However, as mentioned, recursion is covered in depth. In addition, complexity analysis of algorithms is presented in some detail. Chapters 1 and 3—8 present a number of different data structures and the algo-rithms that operate on them. The efficiency of each algorithm is analyzed, and im-provements to the algorithm are suggested.
Different types of recursion are discussed, and a recursive call is dissected. Balanced trees are also included in this chapter. Chapters 9—13 show different applications of data structures introduced in the previous chapters. They emphasize the data structure aspects of each topic under consideration.
Each chapter contains a discussion of the material illustrated with appropriate diagrams and tables. Except for Chapter 2, all chapters include a case study, which is an extended example using the features discussed in that chapter. At the end of each chapter is a set of exercises of varying degrees of difficulty. Except for Chapter 2, all chapters also include programming assignments and an up-to-date bibliography of relevant literature.
Chapters 1—6 excluding Sections 2. These chapters should be studied in sequence. The remaining six chapters can be read in any or-der.

Instructors are encouraged to customize the slides to suit their course needs. The new edition primarily extends the old edition by including material on new topics that are currently not covered. The additions include. Before a program is written, we should have a fairly good idea of how to accom-plish the task being implemented by this program.
Hence, an outline of the program containing its requirements should precede the coding process. The larger and more complex the project, the more detailed the outline phase should be.
The implemen-tation details should be delayed to the later stages of the project. In particular, the details of the particular data structures to be used in the implementation should not be specified at the beginning.
From the start, it is important to specify each task in terms of input and output. At the beginning stages, we should be more concerned with what the program should do, not how it should or could be done. Behavior of the program is more important than the gears of the mechanism accomplishing it.
For example, if an item is needed to accomplish some tasks, the item is specified in terms of operations performed on it rather than in terms of its inner structure. These operations may act upon this item, for example, modifying it, searching for some details in it, or storing something in it. After these operations are precisely specified, the implementation of the program may start. The implementation decides which data structure should be used to make execution most efficient in terms of time and space.
An item specified in terms of op-erations is called an abstract data type. An abstract data type is not a part of a program, because a program written in a programming language requires the definition of a data structure, not just the operations on the data structure. Object-oriented programming OOP revolves around the concept of an object. Objects, however, are created using a class definition.
A class is a template in accor-dance to which objects are created. A class is a piece of software that includes a data Object-Oriented. Functions defined in a class are called methods, member functions, or function members, and variables used in a class are called data members more properly, they should be called datum members.
This combining of the data and related operations is called data encapsulation. An object is an instance of a class, an entity created using a class definition. In contradistinction to functions in languages that are not object-oriented, ob-jects make the connection between data and member functions much tighter and more meaningful. In languages that are not object-oriented, declarations of data and definitions of functions can be interspersed through the entire program, and only the program documentation indicates that there is a connection between them.
In OOLs, a connection is established right at the outset; in fact, the program is based on this connection. An object is defined by related data and operations, and because there may be many objects used in the same program, the objects communicate by exchanging messages that reveal as little detail about their internal structure as neces-sary for adequate communication.
Structuring programs in terms of objects allows us to accomplish several goals. First, this strong coupling of data and operations can be used much better in modeling a fragment of the world, which is emphasized especially by software engi-neering. Not surprisingly, OOP has its roots in simulation; that is, in modeling real-world events.
Second, objects allow for easier error finding because operations are localized to the confines of their objects. Even if side effects occur, they are easier to trace. Third, objects allow us to conceal certain details of their operations from other objects so that these operations may not be adversely affected by other objects. This is known as the information-hiding principle.
In languages that are not object-ori-ented, this principle can be found to some extent in the case of local variables, or as in Pascal, in local functions or procedures, which can be used and accessed only by the function defining them. This is, however, a very tight hiding or no hiding at all. Sometimes we may need to use again, as in Pascal a function f 2 defined in f 1 outside of f 1, but we cannot. Sometimes we may need to access some data local to f 1 without exactly knowing the structure of these data, but we cannot.
Hence, some modification is needed, and it is accomplished in OOLs. An object in OOL is like a watch. As users, we are interested in what the hands show, but not in the inner workings of the watch. We are aware that there are gears and springs inside the watch, but because we usually know very little about why all these parts are in a particular configuration, we should not have access to this mecha-nism so that we do not damage it, inadvertently or on purpose. This mechamecha-nism is hidden from us, we have no immediate access to it, and the watch is protected and works better than when its mechanism is open for everyone to see.
An object discloses only as much as is needed for the user to utilize it. It has a public part that can be accessed by any user when the user sends a message matching any of the member function names revealed by the object.
In this public part, the object displays to the user buttons that can be pushed to invoke the object's operations. The user knows only the names of these operations and the expected behavior. Information hiding tends to blur the dividing line between data and operations.

Я возьму это на себя, - улыбнулась она, вставая.
Сьюзан, - позвал он, задыхаясь. - Ты должна помочь мне выбраться отсюда. Она ничего не понимала.
- Здесь есть кто-нибудь? - Он вошел.
Да, - сказал Беккер. - Мы кое-что упустили. ГЛАВА 13 Токуген Нуматака стоял у окна своего роскошного кабинета на верхнем этаже небоскреба и разглядывал завораживающие очертания Токио на фоне ярко-синего неба. Служащие и конкуренты называли Нуматаку акута саме - смертоносной акулой. За три десятилетия он перехитрил, превзошел и задавил рекламой всех своих японских конкурентов, и теперь лишь один шаг отделял его от того, чтобы превратиться еще и в гиганта мирового рынка.
Вы сейчас же отпустите мисс Флетчер, или я вызову службу безопасности и засажу вас в тюрьму до конца ваших дней. - Вы этого не сделаете, - как ни в чем не бывало сказал Хейл. - Вызов агентов безопасности разрушит все ваши планы.
