Distinct Vowel Counter

You are given a string and you need to check whether the string contains at least one vowel. If it does, count the number of distinct vowels present in the string. The vowels are defined as \(a, e, i, o, u\) and the check is case-insensitive.

If at least one vowel is found, output the message in the format: Contains X distinct vowels., where X is the count of distinct vowels. If no vowels are found, output: No vowels found.
