ProgrammingPythonServer Side Programming In this article, we will see how to right rotate a list from the given rotation number. A list has comma-separated values (items) between square brackets. Important thing about a list is that the items in a list need not be of the same type Let's...
代码(Python3) # Definition for singly-linked list. # class ListNode: # def __init__(self, val=0, next=None): # self.val = val # self.next = next class Solution: def rotateRight(self, head: Optional[ListNode], k: int) -> Optional[ListNode]: # 如果链表为空或者 k 为 0 ,直接...
Given a list, rotate the list to the right bykplaces, wherekis non-negative. For example: Given1->2->3->4->5->NULLandk=2, return4->5->1->2->3->NULL. 解题思路:循环右移一条链表,比如k=2,(1,2,3,4,5)循环右移两位变为(4,5,1,2,3)。由于k值有可能比链表长度大很多,所以先要...
[LeetCode]题解(python):061-Rotate List 题目来源: https://leetcode.com/problems/rotate-list/ 题意分析: 给定一个链表和一个整型k,在链表从右开始数k处开始旋转这个链表。 题目思路: 首先要确定k是在那个地方,然后开始进行链表操作就可以了。要注意的是k有可能比链表长度要长,要将k mod 链表的长度。
[Leetcode][python]Rotate List/旋转链表 题目大意 将一个链表中的元素向右旋转k个位置。 解题思路 参考:http://www.cnblogs.com/zuoyuan/p/3785465.html 解题思路:循环右移一条链表,比如k=2,(1,2,3,4,5)循环右移两位变为(4,5,1,2,3)。由于k值有可能比链表长度大很多,所以先要用一个count变量求出...
最后,对于旋转元素索引 aaa,可以证明经过两步 序列 revert 后,可以正确变换为最终索引 a′a'a′(bbb 可以正确变换为 b′b'b′ 同证): t′=1+offset−a← ∵revert(list,1,offset)a′=1+n−t′←∵revert(list,1,n) =1+n−1−offset+a =n−offset+a \begin{aligned} & t' = 1 + ...
