删除从后往前数的第n个节点 我的做法是将两个指针first,second 先将first指向第n-1个,然后让first和second一起指向他们的next,直到first->next->next为空 最后只要删除second->next /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) : val(x), next(NUL…
原题链接 删除单向链表的倒数第n个结点. 思路: 用两个索引一前一后,同时遍历,当后一个索引值为null时,此时前一个索引表示的节点即为要删除的节点. Runtime: 13 ms, faster than 24.49% of Java class Solution { public ListNode removeNthFromEnd(ListNode head, int n) { ListNode slow=head; ListNode fast=head; for(int i=0;i<n;i…
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;…
