详细说明： This book is a graduate-level textbook on data structures. A data structure is a method1 to realize a set of operations on some data. The classical example is to keep track of a set of items, the items identified by key values, so that we can insert and delete (k ey, item) pairs into the set and find the item with a given key value. A structure supporting these operations is called a dictionary. Dictionaries can be realized in many different ways, with different complexity bounds and various additional operations supported, and indeed many kinds of dictionaries have been proposed and analyzed in literature, and some will be studied in this book. In general, a data structure is a kind of higher-level instruction in a virtual machine: when an algorithm needs to execute some operations many times, it is reasonable to identify what exactly the needed operations are and how they can be realized in the most efficient way. This is the basic question of data structures: given a set of operations whose intended behavior is known, how should we realize that behavior? There is no lack of books carrying the words “data structures” in the title, but they merely scratch the surface of the topic, providing only the trivial structures stack and queue, and then some balanced search tree with a large amount of handwaving. Data structures started receiving serious interest in the 1970s, and, in the first half of the 1980s, almost every issue of the Communications of the ACM contained a data structure paper. They were considered a central topic, received their own classification in the Computing Subject Classification, ...展开收缩
