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
1052 Linked List Sorting (25分) A linked list consists of a series of structures, which are not necessarily adjacent in memory. We assume that each structure contains an integerkeyand aNextpointer to the next structure. Now given a linked list, you are supposed to sort the structures accordi...

[PAT] A1052 Linked List Sorting(重要!) 静态链表 tips 题目可能会有无效结点,即不在题目给出的首地址开始的链表上。因此要先遍历一遍链表,标记出有效结点。 数据里面还有均无效的情况,这时要输出“0 -1”(我想到了这个情况但只输出了0...太无奈了QAQ) AC代码 #define _CRT_SECURE_NO_WARNINGS #include<...
