Part 1 Introduction
It mainly introduces the logical structure and physical structure of the algorithm, and the description and analysis of the algorithm;
Most of the main goals of most computer programs are to say that it is completed, but it is better to store and retrieve information. From the perspective of storage space and runtime, these programs must organize information to support efficient information processing. Therefore, the research data structure and algorithm are effectively supported by the implementation of the procedure, it has become the core issue of computer science.

★ [What is data]
Data (DATA) is a symbol of objective things that refers to all symbols that can be entered into the computer and be processed by the computer program in computer science. This is "raw material" processing of computer program processing. For example, a program using numerical analysis methods to solve the number equation, and its processing object is an integer and real number; a compiler or a processing object of a text handler is a string. Therefore, for computer science, the meaning of data is extremely wide, such as images, sound, etc., can be coded by encoding to the category of data.
