Linear table (array)
The data corresponds to the elements one-to-one except for the first and last other data elements. Connect
Linked list
Non-continuous, non-sequential storage structure on the physical storage unit (non-continuous in memory)
The logical order between data elements is realized through the pointer link sequence in the linked list
The linked list is composed of a series of nodes (the elements in the linked list are called nodes point), the node can be dynamically generated at runtime
The node includes two parts: 1. Data field to store data elements
2. The pointer field that stores the address of the next node (implemented as a pointer)
Linear table is the most basic, simplest, and most commonly used data structure. The relationship between data elements in a linear table is a one-to-one relationship, that is, except for the first and last data elements, other data elements are connected end to end. The linear table has a simple logical structure and is easy to implement and operate. Therefore, the data structure of linear table is widely used in practical applications.
A linked list is a non-continuous and non-sequential storage structure on a physical storage unit. The logical order of data elements is realized through the link order of pointers in the linked list. A linked list consists of a series of nodes (each element in the linked list is called a node), and nodes can be dynamically generated at runtime. Each node consists of two parts: one is the data field that stores data elements, and the other is the pointer field that stores the address of the next node.
Compared with the linear list sequence structure, the linked list is more convenient for insertion and deletion operations.

使用递归方法在C++中找到链表倒数第n个节点Sep 15, 2023 pm 05:53 PM给定一个单链表和正整数N作为输入。目标是使用递归找到给定列表中从末尾算起的第N个节点。如果输入列表有节点a→b→c→d→e→f并且N为4，那么倒数第4个节点将是c。我们将首先遍历直到列表中的最后一个节点以及从递归（回溯）增量计数返回时。当count等于N时，则返回指向当前节点的指针作为结果。让我们看看此的各种输入输出场景-输入-List：-1→5→7→12→2→96→33N=3输出−倒数第N个节点为：2解释−第三个节点是2。输入−列表：-12→53→8→19→20→96→33N=8输出-节点不存
PHP 数组和链表的算法时间复杂度比较May 07, 2024 pm 01:54 PM数组和链表的算法时间复杂度比较：访问数组O(1)，链表O(n)；插入数组O(1)，链表O(1)/O(n)；删除数组O(1)，链表O(n)；搜索数组O(n)，链表O(n)。
将一个以链表表示的数字加1Aug 29, 2023 pm 09:17 PM数字的链表表示是这样提供的：链表的所有节点都被视为数字的一位数字。节点存储数字，使得链表的第一个元素保存数字的最高有效位，链表的最后一个元素保存数字的最低有效位。例如，数字202345在链表中表示为(2->0->2->3->4->5)。要向这个表示数字的链表添加1，我们必须检查列表中最低有效位的值。如果小于9就可以了，否则代码将更改下一个数字，依此类推。现在让我们看一个示例来了解如何做到这一点，1999表示为(1->9->9->9)并添加1应该将其
PHP SPL 数据结构：为你的项目注入速度和灵活性Feb 19, 2024 pm 11:00 PMPHPSPL数据结构库概述PHPSPL（标准php库）数据结构库包含一组类和接口，用于存储和操作各种数据结构。这些数据结构包括数组、链表、栈、队列和集合，每个数据结构都提供了一组特定的方法和属性，用于操纵数据。数组在PHP中，数组是存储一系列元素的有序集合。SPL数组类提供了对原生的PHP数组进行加强的功能，包括排序、过滤和映射。以下是使用SPL数组类的一个示例：useSplArrayObject;$array=newArrayObject(["foo","bar","baz"]);$array
PHP数据结构：链表的魅力，探索动态数据组织Jun 04, 2024 pm 12:53 PM链表是一种数据结构，采用一系列带有数据和指针的节点组织元素，特别适合处理大型数据集和频繁的插入/删除操作。它的基本组成部分包括节点（数据和指向下一个节点的指针）和头节点（指向链表中第一个节点）。常见链表操作包括：添加（尾部插入）、删除（特定值）和遍历。
Go 语言中的链表操作怎样实现？Jun 10, 2023 pm 10:55 PM链表（LinkedList）是一种常见的数据结构，它由一系列结点（Node）组成，每一个结点包含两个关键属性：数据域（Data）和指针域（Next）。其中，数据域用于存储实际数据，指针域则指向下一个结点。通过这种方式，链表以一种灵活的方式存储数据，适用于许多不同的应用场景中。在Go语言中，链表结构也得到了良好的支持。Go的内置标准库中提供了cont
Python程序：在链表的第一个和最后一个位置添加元素Aug 23, 2023 pm 11:17 PM在Python中，链表是一种线性数据结构，它由一系列节点组成，每个节点包含一个值和对链表中下一个节点的引用。在本文中，我们将讨论如何在Python中将元素添加到链表的第一个和最后一个位置。LinkedListinPython链表是一种引用数据结构，用于存储一组元素。它在某种程度上类似于数组，但是在数组中，数据存储在连续的内存位置中，而在链表中，数据不受此条件限制。这意味着数据不是按顺序存储，而是以随机的方式存储在内存中。Thisraisesonequestionthatis,howwecanac
golang如何实现链表Dec 14, 2023 pm 04:37 PM实现链表的方法：1、定义了一个Node结构体来表示链表的节点，每个节点包含一个数据项和一个指向下一个节点的指钁；2、定义了一个LinkedList结构体来表示链表本身，其中包含一个指向链表头节点的指针；3、实现了两个方法，append用于在链表末尾插入节点，printList用于打印链表的元素；4、通过这种方式，可以使用Go语言的结构体和指针来实现链表的基本功能。

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
