All Vowels or Consonants

You are given a string s of length N (where \(1 \leq N \leq 50\)) consisting only of lowercase English letters. Your task is to determine whether all the characters in the string are either vowels or consonants.

If all characters are vowels or all are consonants, output "Yes". Otherwise, output "No".

For example, if s = "aeiou", then the output should be "Yes" since all characters are vowels. And if s = "hello", then the output should be "No" because it contains both vowels and consonants.
