Count Vowels

Write a program that reads a string from standard input (stdin) and counts the number of vowels in the string. Both lowercase and uppercase vowels, i.e., (a, e, i, o, u), should be counted. The string can be empty or contain spaces and other characters. Your solution should output the result to standard output (stdout).

inputFormat

The input consists of a single line containing the string. Note that the string may include spaces.

outputFormat
