题意:删除链表中倒数第N个节点. 法一:递归.每次统计当前链表长度,如果等于N,则return head -> next,即删除倒数第N个节点:否则的话,问题转化为子问题“对head->next这个链表删除倒数第N个节点”,将head的next指针指向该子问题的结果,返回head即可.这个方法时间复杂度高,不推荐. /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next;…

题目:删除链表的倒数第N个节点 难度:Medium 题目内容: Given a linked list, remove the n-th node from the end of list and return its head. 翻译:给定一个链表,删除倒数第n个节点并返回其头部. Example: Given linked list: 1->2->3->4->5, and n = 2. After removing the second node from the end, t…

Level:   Medium 题目描述: Given a linked list, remove the n-th node from the end of list and return its head. Example: Given linked list: 1->2->3->4->5, and n = 2. After removing the second node from the end, the linked list becomes 1->2->3-…

题目描述: 中文: 给定一个链表,删除链表的倒数第 n 个节点,并且返回链表的头结点. 示例: 给定一个链表: 1->2->3->4->5, 和 n = 2. 当删除了倒数第二个节点后,链表变为 1->2->3->5. 说明: 给定的 n 保证是有效的. 进阶: 你能尝试使用一趟扫描实现吗? 英文: Given a linked list, remove the n-th node from the end of list and return its head.…

Given a linked list, remove the nth node from the end of list and return its head. For example, Given linked list: 1->2->3->4->5, and n = 2. After removing the second node from the end, the linked list becomes 1->2->3->5. Note: Given…
