Problem: Given a singly linked list, determine if it is a palindrome. Follow up: Could you do it in O(n) time and O(1) space? Analysis: 判断一个单向链表是否是回文链表,要求O(n)的时间复杂度和O(1)的空间复杂度。 算法有以下几种: 遍历整个链
Given a singly linked list, determine if it is a palindrome. Follow up: Could you do it in O(n) time and O(1) space? 用o(n)的space来创建一个反向的链表,也能AC,时间是36ms,代码如下: class Solution {public:bool isPalind
题目: Given a singly linked list, determine if it is a palindrome. Follow up: Could you do it in O(n) time and O(1) space? 分析: 如果要得到一个在中间的值,可以考虑一个走一步,一个走两步。 代码: O(n)space /*** Defini

Given a singly linked list, determine if it is a palindrome. Follow up: Could you do it in O(n) time and O(1) space? 题目分析:此题难度为easy,但要满足空间O(1),程序一次写对也是不容易的。思路是逆置后一半,中点用快慢指针的方式寻找,然后比较即可 /*** Defin
题目 Given a singly linked list, determine if it is a palindrome. Follow up: Could you do it in O(n) time and O(1) space? 思路 利用双指针法找到链表中点位置,链表中点以后的的元素(不包括中点元素)翻转,再跟链表中点位置以前的元素一一匹配。 代码 /*---------
