题目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.

public class Solution {
    public void deleteNode(ListNode node) {
        if(node.next == null){
            return;
        }
        node.val = node.next.val;
        node.next = node.next.next;
    }
}
