Examples
Example 1:
Input: head = [1,2,3,4], n = 2
Output: [1,2,4]
Example 2:
Input: head = [5], n = 1
Output: []
Example 3:
Input: head = [1,2], n = 2
Output: [2]

You are given the beginning of a linked list head, and an integer n.
Remove the nth node from the end of the list and return the beginning of the list.
sz.1 <= sz <= 300 <= Node.val <= 1001 <= n <= sz
