Count Vowels

Count how many characters of a string are vowels.

Return how many characters of text are vowels.

The vowels are a, e, i, o and u. Both cases count, so A and a are each a vowel. Every other character — consonants, digits, spaces, punctuation — is not.

Constraints

  • 0 ≤ text.length ≤ 100,000
