Reverse Linked List II Problem: Reverse a linked list from position m to n. Do it in one-pass. Note: 1 ≤ m ≤ n ≤ length of list. Example: 题目:逆转m到n位节点顺序,其余部分不变。一次遍历完成。 思路:想哭,明...猜你喜欢LeetCode 92. Reverse Linked List II 问题描述 Reverse a ...
Reverse a linked list. 翻转一个链表 【题目链接】 http://www.lintcode.com/en/problem/reverse-linked-list/ 【题目解析】 这题要求我们翻转[m, n]区间之间的链表。对于链表翻转来说,几乎都是通用的做法,譬如p1 -> p2 -> p3 -> p4,如果我们要翻转p2和p3,其实就是将p3挂载到p1的后面,所以我们需要知...

Reverse a linked list from position m to n. Notice:Given m, n satisfy the following condition: 1 ≤ m ≤ n ≤ length of list. 翻转链表中第m个节点到第n个节点的部分 注意:m,n满足1 ≤ m ≤ n ≤ 链表长度 【题目链接】 http://www.lintcode.com/en/problem/reverse-linked-list-ii/ ...
We can also use recursion to solve this problem. /** * Definition for singly-linked list. * public class ListNode { * int val; * ListNode next; * ListNode(int x) { val = x; } * } */ public class Solution { public ListNode reverseList(ListNode head) { ...
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. 算法分析:其实就是反转链表加了个条件,先找到第m-1个元素,m个元素,第n+1个元素,反转后再连接起来。 public...
