Background Different sites have different password requirements.

You have grown tired of having to think up new passwords to meet all the different rules, so you write a small piece of code to do all the thinking for you.

Kata Task Return any valid password which matches the requirements.

Input:

length = password must be this length flagUpper = must (or must not) contain UPPERCASE alpha flagLower = must (or must not) contain lowercase alpha flagDigit = must (or must not) contain digit Notes Only alpha-numeric characters are permitted The same character cannot occur more than once in the password! All test cases guarantee that a valid password is possible
