Silly strings

You are given the following rules about strings:

1. There can only be an even number of vowels
2. There must be AT LEAST 3 digits
3. There must be AT MOST 3 non-alphanumeric characters
(Defined as not in the set {0…9,a…z,A…Z})
4. There must be no occurrence of the letters ‘b’ or ‘q’ in the string.


Write a program that will determine if the inputted string is valid based on the given rules.
