A linked list can be reversed either iteratively or recursively. Could you implement both? 解法一:(C++) 利用迭代的方法依次将链表元素放在新链表的最前端实现链表的倒置 1classSolution {2public:3ListNode* reverseList(ListNode*head) {4ListNode* newhead=NULL;5while(head){6ListNode* t=head->next;7h...
与数组不同“怼在后面” 这个操作是O(n) 效率很差。 ListNode* reverseList(ListNode*head) {if(!head)returnnullptr;if(!head->next)returnhead; ListNode* c = reverseList(head->next); ListNode* p =c;while(p->next) { p= p->next; } p->next =head; head->next =nullptr;returnc; } 2....
leetcode 206. Reverse Linked List 反转字符串 Reverse a singly linked list. 反转链表,我这里是采用头插法来实现反转链表。 代码如下: /*class ListNode { int val; ListNode next; ListNode(int x) { val = x; } } */ public class Solution { public ListNode reverseList(ListNode head) { if(head...
Another useful function for our linked list data structure isprintNodes, which is used to output data from every node to thecoutstream. The latter one will help us loosely verify the correctness of the reversal function. Note thatprintNodeskeeps the count of nodes during the list traversal and...
206. Reverse Linked List Reverse a singly linked list. 反转一个链表。 思路: 采用头插法,将原来链表重新插一次返回即可。 代码如下: /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) : val(x), next(NULL) {} ...
