linked on

Before I started writing the Linux kernel two-way circular linked list, I had been wondering if I would like to use a long article to describe the Linux kernel two-way circular linked list? After careful consideration, I refused to describe the Linux kernel bidirectional circular linked list in boring words, because for programming languages, I believe that most

What is a linked list. : Chain-type stored linear table, referred to as the list. A list consists of multiple linked list elements called nodes. A chain-type storage structure is formed between nodes through a logical connection. A memory unit that stores nodes that can be contiguous or discontinuous. Logical connections are not related to the physical storage order. The list is divided into two domains:Ran

There are a number of linked lists used in the Linux kernel: doubly linked lists. The management of the processes used in the kernel is achieved through a doubly linked list. So the operation of the list is very common and very important, so the kernel by providing a common method to help us to facilitate the implementation of the double-

Double-linked list definitionA doubly linked list adds a pointer field to a single-linked table node that points to the precursor of the current node. In this way, it is convenient for the successor to find its precursor, and the data sequence of the output terminal node to the beginning node can be realized.Similarly, a doubly

Reference: http://www.itxyz.net/3jk/c/2010/0820/11016.html Recently, I am not too busy. I may be able to organize some things and get some help from my work. 1. Why is linked list used? Array is a collection of similar data, which brings us a lot of convenience and flexibility in programming. However, arrays also have some disadvantages. For example, the size of an array must be specified in advance during definition and cannot be adjusted in the prog

C language implementation of linked list (including dynamic memory allocation) Dynamic Memory Allocation in C language of the linked list I. Why dynamic memory allocation? When we do not learn the linked list, we always use an array to store a large number of data of the same type or structure. For example, if we want to store the scores of a certain student in

We know that an array-type computer will automatically allocate a continuous storage unit to it based on the pre-defined array type and length. The positions and distances of the same array are fixed, that is, the address of any array element can be calculated using a simple formula. Therefore, this structure can effectively perform random access to array elements. However, if an array element is inserted or deleted, a large amount of data is moved, making simple data processing very complicated

Problem description: two unidirectional linked lists are given to find their first public node. The linked list nodes are defined as follows: Struct listnode { Int m_nkey; Listnode * m_pnext; }; Problem Analysis: This is a Microsoft interview question. Microsoft is very fond of linked list-related questions. Therefore, in Microsoft's interview questions,

In my previous blog, "C language implementation of single-linked list (do not take the lead node)," The implementation of a single-linked list of non-lead node 11 operations: such as calculating the length of the list, initialization, create linked list, empty list and so on. However, in actual use, the single-linked l
