Answer 2

I'm not an expert in Ruby, but I know a bit of Regex. You can test each of the criteria "separately", rather than using that loooooong exp as,

- 2 nums: /\d.*?\d/
\d matches a digit
.*? matches as few char as possible (lazy, could match none)
\d matches another digit

- 2 of special char: /[!@#$%&*].*?[!@#$%&*]/
the same meaning

That's it!
