Reverse a linked list from positionmton. Do it in-place and in one-pass. For example: Given1->2->3->4->5->NULL,m= 2 andn= 4, return1->4->3->2->5->NULL. Note: Givenm,nsatisfy the following condition: 1≤m≤n≤ length of list. 解题思路: 这题是Reverse Nodes in k-Group...
我们接下来要做的是,先把Mpre的next域指向NodeM节点的后一个节点; 再把NodeM所在节点移动到NodeN所在节点之后,使得NodeN的next域指向NodeM所在节点,NodeM所在节点next域指向NodeN的next域所指节点; 然后让NodeM指向Mpre的next域指向的节点; 演示图2 然后再重复上面的步骤; 这是NodeM和NodeN相遇,反转完成。 代码...
Reverse Linked List II Reverse a linked list from positionmton. Do it in-place and in one-pass. For example: Given1->2->3->4->5->NULL,m= 2 andn= 4, return1->4->3->2->5->NULL. Note: Givenm,nsatisfy the following condition: 1≤m≤n≤ length of list. 把[m,n]那一段抠...
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 1. 2. 题目大意 给定2 个链表中结点的位置 m, n,反转这个两个位置区间内的所有结...

Reverse Linked List II 中文网站:92. 反转链表 II 问题描述 Given the head of a singly linked list and two integers left and right where left <= right, reverse the nodes of the list from position left to position right, and return the reversed list. Example 1: Input: head = [1,2,3,...
2.每次当newHead = reverseList(head.next)执行完返回时,可以认为head.next所在的节点(假设该节点为A)以及它右边的节点就已经反转好了,所以现在需要处理head和A之间的反转,即要把A指向head,然后head指向None。所以A.next = head,但是这个A节点怎么获取呢,其实A就是head.next,也就是head.next(A).next = head...
Reverse a linked list from position m to n. Do it in one-pass. Example: Input: 1->2->3->4->5->NULL, m = 2, n = 4 Output: 1->4->3->2->5->NULL Note: 1≤ m ≤ n ≤ length of list. 解释下题目: 在一次循环中把链表指定位置倒序 ...
