    Python 3:

    numbers = {*"0123456789"}
lower_case = {*"abcdefghijklmnopqrstuvwxyz"}
upper_case = {*"ABCDEFGHIJKLMNOPQRSTUVWXYZ"}
special_characters = {*"!@#$%^&*()-+"}


def minimumNumber(n: int, password: str) -> int:
    # Return the minimum number of characters to make the password strong
    if n < 3:
        return 6 - n
    characters = {*password}
    return max(
        sum(
            not (characters & char_class)
            for char_class in (numbers, lower_case, upper_case, special_characters)
        ),
        6 - n,
    )
