4.11.1. Password Validator When creating an account, it is often required that the password should fulfil some strength requirements. It should be X characters long, have at least Y digits, contain underscore, hash, and a mixture of lower and capital letters, etc. Your task is to write a method that will validate a given password. The set of rules (requirements) with which you will be verifying the passwords is up to you. 4.11.2. Regex Some people, when confronted with a problem, think "I know, I'll use regular expressions."

Table 4.1 gives some examples of expected results for various input strings. Table 4.1. Expected outputs of regex method expected output input abc 12 cdefg 345 12bb23 cdefg 345 12bbb33 678tt 345 345, 678
