What is a linear table? In response to this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more small partners who want to solve this problem find a simpler and easier way.

Linear tables are the most basic, simplest, and most commonly used data structures. A linear list is a type of data structure where a linear list is a finite sequence of n data elements with the same properties.

The relationship between data elements in a linear table is one-to-one, meaning that all data elements are end-to-end except for the first and last data elements (note that this applies to most linear tables, not all). For example, a circular linked list is also a linear list at the logical level (storage level belongs to chained storage, but the tail pointer of the last data element points to the first node)

defined

A linear list is a type of data structure where a linear list is a finite sequence of n data elements with the same properties. A data element is an abstract symbol whose specific meaning varies from case to case.

In a slightly more complex linear table, a data element can be composed of multiple data items, in which case the data element is often called a record, and a linear table containing a large number of records is also called a file.

The number n in the linear table is defined as the length of the linear table, and n=0 is called an empty table. Each data element has a definite position in a non-empty table. If ai is used to represent a data element, i is called the bit order of data element ai in a linear table.

There is an order pair relation between adjacent elements of a linear table. If (a1,..., ai-1, ai, ai+1,..., an) is used to represent an order table, then ai-1 precedes ai and ai precedes ai+1 in the table, and ai-1 is said to be the immediate predecessor of ai and ai+1 is the immediate successor of ai. When i= 1, 2,…, n-1, ai has one and only one direct successor, and when i=2, 3,…, n, ai has one and only one direct predecessor [1].

classification

When we say "linear" and "nonlinear," we talk only at the logical level, not the storage level, so doubly linked lists and circular lists are still linear lists.

Linear tables can be divided into general linear tables and restricted linear tables at the logical level of data structure. General linear table is also what we usually call "linear table", you can freely delete or add nodes. Restricted linear tables mainly include stacks and queues, and restricted means that operations on nodes are restricted.

advantages

Linear table logic structure is simple, easy to implement and operate. Therefore, the linear table data structure is widely used in practical applications.
