写一个函数删除一个单链表中的节点，

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.

算法设计：

略

Java代码实现：

/** * 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)            return;        else        {            node.val=node.next.val;            node.next=node.next.next;        }    }}
