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 ==…
