Balanced search tree: A search-tree data structure for which a height of O(lg n) is guaranteed when implementing a dynamic set of n items

采用计算机对生产过程进行监视和测量的系统，一般称 为数据采集系统 (Data Acquisition System 简称DAS)，或称为 计算机安全监视系统、计算机信息处理系统、数据采集监视 和处理系统等。 国外最早应用计算机对生产过程进行监视和测量在60年代 初期，据统计，1968年时美国在火电厂应用计算机已多达190 多台，其中70%左右为纯粹的DAS系统，30%左右除DAS系统 以外，少部分具有的运行控制功能

const int maxLen = 128; class String { int curLen; //串的当前长度 char *ch; //串的存储数组 public: String ( const String& ob ); String ( const char * init );

1 Preliminaries 1. Terminology Lineal Tree Pedigree Tree ( binary tree )

【Definition】An algorithm is a finite set of instructions that, if followed, accomplishes a particular task. In addition, all algorithms must satisfy the following criteria: (1) Input There are zero or more quantities that are externally supplied

1 Equivalence Relations 【Definition】A relation R is defined on a set S if for every pair of elements (a, b), a, b S, a R b is either true or false. If a R b is true, then we say that a is related to b

Exercises Linear equations for the consumption and saving schedule take the general form C=a + bY and S=-a+(1-b)Y, where C, S and Y are consumption, saving and national income respectively. (1) Use the given data to develop specific numerical values for the consumption and saving equations. Write the using these values

Symbol table: major inherited attribute and major data structure in a compiler Principal operations: – Insert: store the information provided by name declarations when processing these declarations – Lookup: retrieve the information associated to a name when that name is used in the associated code

The memory of a typical computer: A register area; Addressable Random access memory (RAM): A code area; A data area. The code area is fixed prior to execution, and can be visualized as follows:
