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的形式,尤其是题目中所规定

In this article, we will learn how to sort a linked list using merge sort algorithm. It is one of the most preferred algorithms to sort a linked list because slow pointer random access makes the performance of other algorithms worse (for example: quicksort and heapsort). ...
covered many sorting algorithms, and we could do many of these sorting algorithms on linked lists as well. Let's take selection sort for example. In selection sort we find the lowest value, remove it, and insert it at the beginning. We could do the same with a linked list as well, ...

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...
