Given a lowercase English letter c, determine whether it is a vowel. Here, there are five vowels in the English alphabet: a, e, i, o and u.

-----Constraints-----
 - c is a lowercase English letter.

-----Input-----
The input is given from Standard Input in the following format:
c

-----Output-----
If c is a vowel, print vowel. Otherwise, print consonant.

-----Sample Input-----
a

-----Sample Output-----
vowel

Since a is a vowel, print vowel.
