Palindrome Linked List 1,题目要求 Given a singly linked list, determine if it is a palindrome. 给出一个单链表,确定它是否是回文。 2,题目思路 对于这道题,是判断一个链表是否构成回文形式。 一般来说,判断一个字符串或者一个数组是不是回文比较简单,直接两端向中间依次进行比较即可,但是链表是个比较特殊...
【1052】Linked List Sorting (链表) 0.知识回顾 (1)【A1032】找出两条链表的最早公共结点。 (2)静态链表的定义、初始化、遍历。 (3)链表结点结构体的sort排序(使用cmp参数)。 1.题目 https://pintia.cn/problem-sets/994805342720868352/problems/994805425780670464 按照链表结...

PAT 1052 Linked List Sorting A linked list consists of a series of structures, which are not necessarily adjacent in memory. We assume that each structure contains an integer keyand a Next pointer to the next struc...PAT 1052 Linked List Sorting 注意两点: 判断vector长度是否为0,也就是...
1052 Linked List Sorting(排序) 思路:s t r u c t + struct+struct+排序。 坑点: 1.答案只包含从原链表中头结点开始的结点,有点结点不在原链表上不用考虑。 2.头结点可能不存在,直接输出0 − 1 0 -10−1。 AI检测代码解析 #include<bits/stdc++.h> ...
