Rotate List 旋转链表 首尾相连,旋转断开 Rotate List 旋转链表 Given theheadof a linked list, rotate the list to the right bykplaces. Input: head = [1,2,3,4,5], k = 2 Output: [4,5,1,2,3] 向右旋转1步:5->1->2->3->4->NULL 向右旋转2步:4->5->1->2->3->NULL 首尾相连,...
譬如上面这个例子,k等于2,我们遍历到链表结尾之后,连接1,然后遍历5 - 2 % 5个字节,断开环,下一个节点就是新的链表头了。 代码如下: class Solution { public: ListNode *rotateRight(ListNode *head, int k) { if(!head || k == 0) { return head; } int n = 1; ListNode* p = head; //得...
