Given a linked list, reverse the nodes of a linked list k at a time and return its modified list. If the number of nodes is not a multiple of k then left-out nodes in the end should remain as it is. You may not alter the values in the nodes, only nod…

问题描述:1->2->3->4,假设k=2进行反转,得到2->1->4->3:k=3进行反转,得到3->2->1->4 算法思想:基本操作就是链表反转,将k个元素当作滑动窗口,依次进行反转. public class ReverseNodesInKGroup { public ListNode reverseKGroup(ListNode head, int k) { if (k == 1 || head == null || head.next ==…

给出一个链表,一次翻转 k 个指针节点,并返回修改后的链表.k 是一个正整数,并且小于等于链表的长度.如果指针节点的数量不是 k 的整数倍,那么最后剩余的节点应当保持原来的样子.你不应该改变节点的值,只有节点位置本身可能会改变.题目应当保证,仅使用恒定的内存.例如,给定这个链表:1->2->3->4->5当 k = 2时,应当返回: 2->1->4->3->5当 k = 3时,应当返回: 3->2->1->4->5详见:https:/…
