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.

删除链表的节点:刚开始题目理解错误,这题以前有个老师讲过类似的题目。

public void deleteNode(ListNode node) {

	 node.val = node.next.val;
	node.next = node.next.next;

}
问题是这里的:

	node.next = node.next.next;
可不可以换成:
	node = node.next;
