Strong Password

Time allowed: 25 mins

Create a function that takes a candidate password and returns the minimum number of extra characters needed to make it 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(“#Edabit”) ➞ 1
strongPassword("W1llth!spass?") ➞ 0

Notes

Try solving this without RegEx.
