Swap Halves

Write a function swap_halves(items) that takes a tuple of even length and returns a new tuple in which the first and second halves have been swapped.

Example

swap_halves((1, 2, 3, 4))  ->  (3, 4, 1, 2)

Your task

Implement this function:

def swap_halves(items: tuple) -> tuple:

Write the function only — the arguments are read for you and the return value is printed automatically.

Arguments arrive as one Python literal per line, in this order: items.

Example

Input

(1, 2, 3, 4)

Output

(3, 4, 1, 2)
