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
the linked list should become
/**
* 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) {
if(node!=null&&node.next!=null){
node.val=node.next.val;
node.next=node.next.next;
}
}
}大概思路就是 把后一个的value给前面一个
把后一个的指针也给前面一个
Supposed the linked list is
1 -> 2 -> 3 -> 4and you are given the third node with value
3,
the linked list should become
1 -> 2 -> 4after calling your function.
/**
* 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) {
if(node!=null&&node.next!=null){
node.val=node.next.val;
node.next=node.next.next;
}
}
}大概思路就是 把后一个的value给前面一个
把后一个的指针也给前面一个
