王几行xing:【Python-转码刷题】LeetCode 203 移除链表元素 Remove Linked List Elements 提到翻转,熟悉Python的朋友可能马上就想到了列表的 reverse。 1. 读题 2. Python 中的 reverse 方法 list1 = list("abcde") list1.reverse() list1 [Out: ] ['e', 'd', 'c', 'b', 'a'] 2.1 reverse 在...

x):self.val=xself.next=None# 该函数接受原始链表的头节点,返回反转后的链表的头节点defreverseList(head):# 定义两个指针,一个记录当前指标所在的位置,反转的时候,意味着需要把当前节点cur指向它的上一个节点;# 而因为是单链表的缘故,所以当前节点是不知道它的前一个节点是哪一个的,需要一个pre指针去指向...
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-Grou...

给你单链表的头节点 head ,请你反转链表,并返回反转后的链表。 示例1: 输入:head = [1,2,3,4,5] 输出:[5,4,3,2,1] 示例2: 输入:head = [1,2] 输出:[2,1] 示例3: 输入:head = [] 输出:[] 提示: 链表中节点的数目范围是 [0, 5000] -5000 <= Node.val <= 5000 进阶:链表可...
