2.Ex1 Password validation.js

/* Password Validation

Write a program that should check if each password in the input array 
contains a valid password by satisfying below criterias and return a
new array with "true" or "false" booleans denoting which password is
acceptable.

Criterias:
  1) 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 symbols ("!", "#", "$", "%", ".")

  2) Passwords must not be any previous password in the passwords input array.

Example:

Let's assume function receive following passwords
 ["tytT3729.", "fhD!yrjj", "ttkTuwer3", "DVYYEYY!5", "qwbfj76%", "Pl3!", "tytT3729.", "12qw"]

Expected result after validation should be
 [true, false, false, false, false, false, flase, false]

The belows are invalids because
  - "fhD!yrjj"  doesn't contain number
  - "ttkTuwer3" doesn't contain special symbol
  - "DVYYEYY!5" doesn't contain lowercase letter
  - "qwbfj76%"  doesn't contain uppercase letter
  - "Pl3!"      doesn't contain at least 5 characters
  - "tytT3729." is valid as an individual password, but already appeared in the password array
  - "12qw"      doesn't contain uppercase letter, special symbol and less than 5 characters long
