Instructions

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:

const numbers = "0123456789"
const lower = "abcdefghijklmnopqrstuvwxyz"
const upper = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
const special = "!@#$%^&*()-+"

Examples

strongPassword(“Ed1”) ➞ 3

strongPassword(“#Innokodakademija”) ➞ 1

strongPassword("W1llth!spass?") ➞ 0
