You are asked to design the function minimum that takes 3 integer values as arguments and prints the smallest of those values. What would the function signature (header) look like? def minimum(n1.int, n2:int, n3:int) -> int: def minimum(n1:int, n2:int, n3:int) -> None: def minimum(n1:int, n2:int, n3:int) -> min:int: def minimum(n1, n2, n3.int): def minimum(n1.int, n2:int, n3.int): def minimum(n1, n2, n3:int) -> int
