Counting Vowels

Several English sentences are given. Write a program that counts how many vowels each sentence contains.

The vowels are a, e, i, o, and u. Both uppercase and lowercase letters count as vowels.

The input consists of multiple test cases. Each test case is one line containing uppercase and lowercase English letters, commas (,), periods (.), exclamation marks (!), question marks (?), and spaces. Each line has at most 255 characters.

The final line of input contains only the single character #. Do not process this line.

For each test case, output the number of vowels in that line on its own line.
