Each consonant (the letters except the vowels) must be lowercase.
For example, "ApplE" is the VCW of "aPPle", "jUhUA" is the VCW of "Juhua".

Input The first line of the input contains an integer T (T<=20) which means the number of test cases.
For each case, there is a line contains the word (only contains uppercase and lowercase). The length of the word is not greater than 50.

Output For each case, output its Vowel-Counting-Word.
Sample Input

解題思路：水題一枚，字符大小寫轉化問題。

AC代碼：

#include 
#include 
#include 
using namespace std;

int main(){
//    freopen("in.txt", "r", stdin);
    int t;
    string s;
    while(scanf("%d", &t)!=EOF){
        cin>>s;
        for(int i=0; i='a' && s[i]<='z')  s[i] -= 32;
                printf("%c", s[i]);    
            }
            else{
                if(s[i]>='A' && s[i]<='Z')  s[i] += 32;
                printf("%c", s[i]);    
            }
        }
        printf("\n");    
    }
    return 0;
}
