链表结构在redis中可以存储多个字符串,并且是有序的,能够存储2的32次方-1个节点(超过40亿个节点),此外链表还是双向的,因此可以从左到右或者从右到左进行遍历它存储的节点。 **链表结构的优点是插入和删除非常方便快速,而查询遍历则性能非常低下。**新增或者删除节点只需要改变节点的指向指针即可,

文章目录概述Redis 关于链表的命令概述链表结构是 Redis 中一个常用的结构,它可以存储多个字符串它是有序的能够存储2的32次方减一个节点(超过 40 亿个节点)Redis 链表是双向的,因此即可以从左到右,也可以从右到左遍历它存储的节点链表结构查找性能不佳,但 插入和删除速度很快由于是双向链表,所以只能够从左到右,或者从右到左地访问和操作链表里面的数据节点。 但是使用链表...

Given a linked list, determine if it has a cycle in it.Follow up:Can you solve it without using extra space?CICT上有差不多的原题, 1. 初始化两个iterator都等于head, 设为a,b。2. 每次迭代,a走一步,b走两步。3. 如果a或者b走到null那就说明链表没有环,返回fa

解题思路:三指针,跟踪算法的步骤例如以下:
代码例如以下:
/**
* Definition for singly-linked list.
* struct ListNode {
* int val;
* ListNode *next;
* ListNode(int x) : val(x), next(NULL) {}
* };
