Remove Nth Node From End of List

Given a list of values and an integer n, remove the n-th node from the end of the list and return the result as space-separated values.

Input:

1,2,3,4,5
2

Output:

1 2 3 5

Reasoning:

The input list is $1, 2, 3, 4, 5$ and $n = 2$ , meaning we need to remove the 2nd node from the end.
To find the node to remove, we calculate its position from the start: $5 - 2 + 1 = 4$ , so the 4th node from the start needs to be removed.
The node at the 4th position has a value of $4$ , which is removed from the list.
The resulting list is $1, 2, 3, 5$ , which is returned as space-separated values: $1 2 3 5$ .
