Replace Vowels

Given a string S, replace every vowel in the string with the next vowel in the sequence a → e, e → i, i → o, o → u, and u → a. The replacement must be performed in a case-sensitive manner so that the case of each character is preserved. For example, if a vowel is uppercase in the input, its replacement should also be uppercase.

Your program should read the input from standard input (stdin) and output the transformed string to standard output (stdout).

More formally, for every vowel v in the string, replace it by:

\[ \text{next}(v)=\begin{cases} e, & \text{if } v=a,\\ i, & \text{if } v=e,\\ o, & \text{if } v=i,\\ u, & \text{if } v=o,\\ a, & \text{if } v=u, \end{cases} \]

and similarly for the uppercase vowels.

inputFormat

The input consists of a single line containing a non-empty string S which may include letters, digits, and other characters.

outputFormat

Output the transformed string after replacing each vowel with its subsequent vowel in the sequence.
