237. Delete Node in a Linked List

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.

含义：给定列表中的某一个节点，删除该节点

 

    public void deleteNode(ListNode node) {
    node.val=node.next.val;
    node.next=node.next.next;        
    }
