def removeNthFromEnd(self, head, n): 类的一个方法,用于删除链表的倒数第n个节点。 def remove(head): 一个内部定义的递归函数,用来递归地遍历链表,同时找到并删除指定的节点。 递归函数 remove 这个递归函数是解决方案的核心。递归意味着函数会调用自身来解决问题的子部分,直到达到一个基本情况(base case),然...
public ListNode removeNthFromEnd(ListNode head, int n) { int len = 0; ListNode h = head; while (h != null) { h = h.next; len++; } //长度等于 1 ,再删除一个结点就为 null 了 if (len == 1) { return null; } int rm_node_index = len - n; //如果删除的是头结点 if (rm...
After removing the second node from the end, the linked list becomes 1->2->3->5. Note: Given n will always be valid. Try to do this in one pass. 移除链表中倒数第n个节点; 写一个函数来确定要删除的是第几个节点,方法是获取链表总长度len,那么我们要删除的就是第 nth = len - n 个节点...
After removing the second node from the end, the linked list becomes 1->2->3->5. Note: Given n will always be valid. Follow up: Could you do this in one pass? 思路: 这道题让我们移除链表倒数第N个节点,限定n一定是有效的,即n不会大于链表中的元素总数。还有题目要求我们一次遍历解...
