Special Vowel Pairs String

Special Vowel Pairs String

Given a string, determine whether it is a "special" string. A string is considered special if each vowel (a, e, i, o, u) appears an even number of times. Non-vowel characters are ignored.

Formally, let the count of each vowel be denoted by \(c\). The string is special if and only if \(c \% 2 = 0\) for every vowel in \(\{a, e, i, o, u\}\).

inputFormat

A single line containing the string to be checked. The input is provided via standard input (stdin).

outputFormat

Output either "True" if the string is special or "False" otherwise on standard output (stdout).## sample
