Create a function that determines the minimum number of characters needed to make a strong password.

A password is considered strong if it satisfies the following criteria:

• Its length is at least 6.
• It contains at least one digit.
• It contains at least one lowercase English character.
• It contains at least one uppercase English character.
• It contains at least one special character: !@#$%^&*()-+

Types of characters in a form you can paste into your solution:

static final String numbers = "0123456789";
static final String lower_case = "abcdefghijklmnopqrstuvwxyz";
static final String upper_case = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
static final String special_characters = "!@#$%^&*()-+";

Examples

strongPassword(“Ed1”) ➞ 3

strongPassword(“#Edabit”) ➞ 1

strongPassword("W1llth!spass?") ➞ 0
