Write a function to delete a node (except the tail) in a singly linked list, given only access to that node.
Supposed the linked list is 1 -> 2 -> 3 -> 4
and you are given the third node with value 3
,
the linked list should become 1 -> 2 -> 4
after calling your function.
思路:这道题只给出要删除的节点,没有给出链表头节点,很简单,把下一个节点的值赋给要删除的节点,然后把下一个节点从链表中删除就好了
/**
* Definition for singly-linked list.
* public class ListNode {
* int val;
* ListNode next;
* ListNode(int x) { val = x; }
* }
*/
public class Solution {
public void deleteNode(ListNode node) {
ListNode h1=node;
ListNode h2=h1.next;
h1.val=h2.val;
h1.next=h2.next;
}
}
