////////////////////////////////////////////////Delete Node in a Linked List///////////////////////////////////////////
// Write a function to delete a node in a singly-linked list. You will not be given access to the head of the list, instead
// you will be given access to the node to be deleted directly.
// It is guaranteed that the node to be deleted is not a tail node in the list.
// 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.
// Example 3:
// Input: head = [1,2,3,4], node = 3
// Output: [1,2,4]
// Example 4:
// Input: head = [0,1], node = 0
// Output: [1]
// Example 5:
// Input: head = [-3,5,-99], node = -3
// Output: [5,-99]
