I. Definition of data structures: figures and structures

A class of data consists of multiple data objects, the smallest unit of which is the data element, but the data object is the unit of concern for this book of data structures.

Structure is divided into logical structure and physical structure. The logical structure is problem-oriented, including set structure, linear structure, tree structure and graphic structure. And the physical structure is the storage structure, including the sequential storage structure and the link storage structure two kinds. A linked storage structure represents a logical structure between data objects through pointers.

II. Abstract data types

Abstract data type (ADT) refers to a mathematical model and a set of operations defined on the model. Programmers can define themselves in the process of writing a program.

Class is over! Chapter Two----algorithm goodbye.
