Leetcode: Insertion Sort List 题目:Sort a linked list using insertion sort. 即使用插入排序对链表进行排序。 思路分析: 插入排序思想见《排序(一):直接插入排序 》 C++参考代码: /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) ...
利用插入排序的算法即可。注意操作指针。 3、代码 1ListNode* insertionSortList(ListNode*head) {2if(head == NULL || head->next ==NULL)3returnhead;45ListNode *dummy =newListNode(0);6dummy->next =head;7ListNode *pre =dummy;8ListNode *p =head;9ListNode *pn = head->next;1011while(pn !=NU...

https://leetcode.com/problems/insertion-sort-list/ 题目: Sort a linked list using insertion sort. 思路: 头插法。用头结点可以简化插入链表时候的操作,因为要考虑插入链表中间和表头两种情况,插入表头时,head就要更新,还要判断pre指针是否为空 算法: public ListNode insertSortList(ListNode head, ListNode t)...

[LeetCode] Insertion Sort List 简介:Sort a linked list using insertion sort.解题思路 对于得到结点current的插入位置,从头结点开始遍历,直到遍历到值大于等于节点current的结点,然后将从该结点到current的前驱结点的所有结点的值依次和current结点的值交换,从而达到将该节点插入所遍历到的位置的目的。实现代码/***...
