- update node.val
- Link curr.next to curr.next.next

```
/*
LeetCode
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.

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