"易懂详细的数据结构第三章：栈和队列课件"

The third chapter of the data structure courseware covers the topics of stacks and queues. These concepts are presented in a way that is more easily understandable than the information provided in the textbook. The courseware delves into the detailed explanations of these concepts, providing a comprehensive understanding of the material. The chapter begins with an introduction to the concept of a stack, denoted by the symbol (*), followed by the discussion of queues, also denoted by the symbol (*). The practical applications of stacks and queues are then explored. The abstract data type definition for a stack is presented in section 3.1.1, followed by the representation and algorithm implementation of a stack, denoted by (*). The stack is defined as a type of linear table that only allows insertions and deletions at one end. The end where these operations are allowed is known as the stack top, while the other end is referred to as the stack bottom. The operation of inserting an element into the stack is called "push", while the operation of removing an element from the stack is called "pop". A stack is considered empty when it contains no data elements. The concept of "last in, first out (LIFO)" is used to organize data within a stack, hence its alternate name of a "last in, first out" linear table. The ADT Stack is defined as follows: - Data Object: D={ai|ai∈ElemSet,i=1,2,…,n,n>=0} - Data Relationship: R1={<ai-1,ai>|ai-1,ai ∈D,i=2,…,n}, where an is the top of the stack and a1 is the bottom - Basic Operations: InitStack(S);... Overall, the chapter provides a clear and comprehensive understanding of stacks and queues, covering their definitions, representations, and practical applications with a greater level of detail and clarity compared to the textbook. The concepts are broken down into easily understandable explanations, making it easier for students to grasp the material and apply it in practical scenarios.
