Given a list, rotate the list to the right by k places, where k is non-negative. For example: Given 1->2->3->4->5->NULL and k = 2, return 4->5->1->2->3->NULL. SOLUTION 1: 重点就是,要先变成循环链表,end.next =head;再执行ListNode headNew =pre.next;否则,当n = 0的时...

由于一开始看错题目,以为rotate的部分要逆置。所以这里还是post出逆置的code。 AI检测代码解析 # Definition for singly-linked list. # class ListNode(object): # def __init__(self, x): # self.val = x # self.next = None class Solution(object): def reverse(self, head): org_head = head cur...

61. 旋转链表 - 给你一个链表的头节点 head ,旋转链表,将链表每个节点向右移动 k 个位置。 示例 1: [https://assets.leetcode.com/uploads/2020/11/13/rotate1.jpg] 输入:head = [1,2,3,4,5], k = 2 输出:[4,5,1,2,3] 示例 2: [https://assets.leetcode.com
Note that the explanation of this method under the solution section on Leetcode is wrong: It has nothing to do with whether n%k = 0 or not. Though the issue will occur when n%k = 0, it is because n and k are coprime, not n%k = 0. For instance, n = 6, k = 4, n%k =...
