/*
Password Validation

Write a program that should check if a password is valid
and returns a boolean

To be valid, a password must:
- Have at least 5 characters.
- Have at least one English uppercase letter (A-Z)
- Have at least one English lowercase letter (a-z)
- Have at least one number (0-9)
- Have at least one non-alphanumeric symbol ("!", "#", "$", "%", ".", "*", "&")
- Must not be any previous password in the passwords array.

You must breakdown this problem in order to solve it. Find one test case first and get that working
