/**
 * 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.
 *
 * Given linked list -- head = [4,5,1,9], which looks like following:
 *
 * Example 1:
 * Input: head = [4,5,1,9], node = 5
 * Output: [4,1,9]
 * Explanation: You are given the second node with value 5, the linked list should become 4 -> 1 -> 9 after calling your function.
 *
 * Example 2:
 * Input: head = [4,5,1,9], node = 1
 * Output: [4,5,9]
 * Explanation: You are given the third node with value 1, the linked list should become 4 -> 5 -> 9 after calling your function.
 *
 * Note:
 * The linked list will have at least two elements.
 * All of the nodes' values will be unique.
 * The given node will not be the tail and it will always be a valid node of the linked list.
 * Do not return anything from your function.
