Leetcode 25. Reverse Nodes in k-Group 以每组k个结点进行链表反转(链表) 题目描述 已知一个链表,每次对k个节点进行反转,最后返回反转后的链表 测试样例 Input: k = 2, 1->2->3->4->5 Output: 2->1->4->3->5 Input: k = 3, 1->2->3->4->5 Output: 3->2->1->4->5 详细分析 按照题目要求…

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…

题目链接: https://leetcode.com/problems/reverse-nodes-in-k-group/?tab=Description   Problem :将一个有序list划分为k个组,并且每个组的元素逆置   链表操作 :递归算法  每次寻找到该组的尾部,然后进行逆置操作,返回头部,这样每次递归操作之后能够进行下一次的逆置操作. 链表操作画图比较形象!!!! 对于递归算法:找到共同点,找到程序退出点,注意特殊情况 本题中,共同点为每组为k个节点,并且每组进行的操作均为逆…
