为了记录NodeM的前驱节点,我们新建一个虚拟节点,使得该节点的next域指向head; 代码语言:javascript 代码运行次数:0 运行 AI代码解释 ListNode pre=newListNode(0); 我们并不移动pre这个节点,因为在移动的过程中会改变pre存储的地址,我们再新建一个Mpre; 代码语言:javascript 代码运行次数:0 运行 AI代码解释 ListNode ...
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. https://leetcode.com/problems/reverse-link...

In this article, we are going to see how to reverse a single linked list? This problem has come to coding round of Amazon, Microsoft. Submitted by Radib Kar, on December 02, 2018 Problem statement: Given a linked list reverse it without using any additional space (In O(1) space ...
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: AI检测代码解析 /*class ListNode { int val; ListNode next; ListNode(int x) { val = x; } } */ public class Solution { public ListNode reverseList(ListNode head) ...
Given a linked list, reverse the nodes of a linked list k at a time and return its modified list. k is a positive integer and is less than or equal to the length of the linked list. If the number of nodes is not a multiple of k then left-out nodes in the end should remain as...
