https://leetcode-cn.com/problems/delete-node-in-a-linked-list/ 非常巧妙的一道题。 题目没有给head,心想没有head我怎么才能找到要删除的值对应的节点呢? 仔细一看,题中函数的参数给的不是值,而是要删除的节点node。反而降低了解题难度: 1. 把node.next的值赋给node 2. 把node.next指向node.next.next ...
Can you solve this real interview question? Delete Node in a Linked List - There is a singly-linked list head and we want to delete a node node in it. You are given the node to be deleted node. You will not be given access to the first node of head. Al
编写一个函数来删除单链表中的节点(尾部除外),只允许访问该节点。例如: 鉴于链表 - head = [4,5,1,9],如下所示: 4 - > 5 - > 1 - > 9 输入:head = [4,5,1,9],node = 5 输出:[4,1,9] 说明:您将获得值为5的第二个节点,即链表调用你的函数后应该变成4 - > 1 - > 9。 输入:head...
在LeetCode 0237题中,如何处理只有一个节点的链表? Delete Node in a Linked List Desicription Write a function to delete a node (except the tail) in a singly linked list, given only access to that node. Given linked list – head = [4,5,1,9], which looks like following: ...

1 <= Node.val <= 10 ^ 5 样例 思路:快慢指针/双指针 本题是LeetCode 876 - 链表的中间结点和LeetCode 203 - 移除链表元素的加强版,数据范围加大,并需要删除中间结点。 对于链表的题目,一般都可以使用一个哨兵结点。 本题使用哨兵结点,方便处理删除头结点这种边界情况。
