Description

In English, a vowel is one of the letters a, e, i, o, and u. Of course, a vowel may
be uppercase as well as lowercase. Your task here is to count the vowels in a sentence.

Input

Input for this problem is a series of sentences, each consisting of a sequence of words
separated by spaces and/or commas (,) and ending in a full stop (.), exclamation
mark (!), or question mark (?). Each sentence contains no more than 255 characters,
and appears on a line of its own. Input is terminated by a single # on a line of its own.
This line should not be processed.

Output

Output will be a single integer for each input line, the number of vowels (upper or lower
case) found in the sentence. Each output must be on a line of its own.
