数据元素信息和指针信息组成该数据元素的存储映像,这就是节点(Node)。 数据域也可使用data表示,指针域使用next表示。 这样线性表就通过每个结点的指针域形成了一根“链条”,也就是我们所说的“链表”。如果结点的引用域只存储该节点直接后继节点的指针域,则该链表称为单链表(Singly Linked List)。单链表结构如下图...
单向链表（又名单链表、线性链表）是链表的一种，其特点是链表的链接方向是单向的，对链表的访问要通过从头部开始，依序往下读取。代码：#include <stdio.h>#include <stdlib.h>#include <stdbool.h>/** * 定义数据结构 */typedef struct slist_node { void *data; struct slist_node *next;} slis...

In this tutorial, we’ll learn how to find a cycle starting node in a linked list. Also, we’ll analyze the different time and space complexities of each approach. Moreover, we’ll look at the most efficient algorithm and prove it. Furthermore, we’ll prove its linear time complexity....
