3. The question

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.

 1     // Accepted
 2     public void deleteNode(ListNode node) {
 3         
 4         if(node == null || node.next == null)
 5         {
 6             return;
 7         }
 8         node.val = node.next.val;
 9         node.next = node.next.next;
10     }
