Print the count of vowels that match their reverse positions in the input string. For example, in the string 'A man, a plan, a canal, Panama', the vowels in reverse order are 'amaaaana', which matches the positions: 'a' at index 0 matches 'a' at index 35, 'a' at index 1 matches 'a' at index 30, etc.
Input Format:
A single line of text containing the input string.
Output Format:
An integer representing the count of vowels that match the criteria.
