Problem:
 Score : 100 points    Problem Statement 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 1 a      Sample Output 1 vowel  Since a is a vowel, print vowel .       Sample Input 2 z      Sample Output 2 consonant       Sample Input 3 s      Sample Output 3 consonant
