    19 - Remove Nth Node From End of List\.

    Medium

    Given the head of a linked list, remove the nth node from the end of the list and return its head.

    Example 1:

    Input: head = 1,2,3,4,5, n = 2

    Output: 1,2,3,5

    Example 2:

    Input: head = 1, n = 1

    Output: []

    Example 3:

    Input: head = 1,2, n = 1

    Output: 1

    Constraints:

    • The number of nodes in the list is sz.

    • 1 <= sz <= 30

    • 0 <= Node.val <= 100

    • 1 <= n <= sz

    Follow up: Could you do this in one pass?
