Reverse a linked list from position m to n. Do it in-place and in one-pass. For example:Given 1->2->3->4->5->NULL, m = 2 and n = 4, return 1->4->3->2->5->NULL. Note:Given m, n satisfy the following condition:1 ≤ m ≤ n ≤ lengt…
Reverse a singly linked list. 代码如下: the iterative solution:(c++) /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) : val(x), next(NULL) {} * }; */ class Solution { public: ListNode* reverseLis…
Reverse a linked list from position m to n. Do it in one-pass. Note: 1 ≤ m ≤ n ≤ length of list. Example: Input: 1->2->3->4->5->NULL, m = 2, n = 4 Output: 1->4->3->2->5->NULL 很奇怪为何没有倒置链表之一,就来了这个倒置链表之二,不过猜也能猜得到之一就是单纯的倒置整个链表,而这…

1. Reverse Linked List 题目链接 题目要求: Reverse a singly linked list. Hint: A linked list can be reversed either iteratively or recursively. Could you implement both? 初想用递归来实现应该会挺好的,但最终运行时间有点久,达到72ms,虽然没超时.具体程序如下: /** * Definition for singly-linked list. *…
Reverse a linked list from position m to n. Do it in-place and in one-pass. For example: Given 1->2->3->4->5->NULL, m = 2 and n = 4, return 1->4->3->2->5->NULL. Note: Given m, n satisfy the following condition: 1 ≤ m ≤ n ≤ le…
Reverse a singly linked list. Hint: A linked list can be reversed either iteratively or recursively. Could you implement both? 反向链表,分别用递归和迭代方式实现. 递归Iteration: 新建一个node(value=任意值, next = None), 用一个变量 next 记录head.next,head.next指向新node.next,新 node.next…
Reverse Linked List,一道有趣的题目.给你一个链表,输出反向链表.因为我用的是JavaScript提交,所以链表的每个节点都是一个对象.例如1->2->3,就要得到3->2->1. 1.数组构造 一个很容易想到的方法是用数组保存新构造每个节点,然后反向构造链表,输出: var reverseList = function(head) { var ans = []; while (head) { var node = new ListNode(head.val);…
Reverse Linked List II Reverse a linked list from position m to n. Do it in-place and in one-pass. For example:Given 1->2->3->4->5->NULL, m = 2 and n = 4, return 1->4->3->2->5->NULL. Note:Given m, n satisfy the following cond…
