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…

题目 翻转链表 II 翻转链表中第m个节点到第n个节点的部分 样例 给出链表1->2->3->4->5->null, m = 2 和n = 4,返回1->4->3->2->5->null 注意 m,n满足1 ≤ m ≤ n ≤ 链表长度 挑战 在原地一次翻转完成 解题 九章中的程序 /** * Definition for ListNode * public class ListNode { * int val; * ListNode next;…
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…

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 根据经验,先建立一个虚结点dummy node,连上原链表的头结点,这样的话就算头结点变动了,我们还…
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 题意: 给定一个链表,反转第m~n个节点. 反转链表的一般思路 Solution1: 1.用指针找到…
