Basic concepts and algorithms and algorithms of data structure--from "new data structure exercises and analysis" (Li Chunbao)

storage structures, and the sequential storage structure is typically described by means of an array of computer programming languages.(2) Chain-store methodThe method is to store the data elements in any storage unit, not requiring the logically adjacent nodes to be adjacent to the physical location, and the logical relationship between the nodes is represented by additional pointer fields. The resulting storage representation, known as a chained storage structure, is typically described by me

set of operations on this collection. Abstract data type referred to as ADT Refers to a mathematical model and a set of operations defined on this mathematical model. ADT has two important characteristics: Data abstraction: When using ADT to describe an entity handled by a program, the emphasis is on its intrinsic characteristics, its ability to function, and its interface with external users (that is, using his method for the world) Data encapsulation: Separates the external characteristics of
