Vowel Counting

Problem Description

The "Vowel-Counting-Word"(VCW), complies with the following conditions.
Each vowel in the word must be uppercase.
Each consonant (the letters except the vowels) must be lowercase.
For example, "ApplE" is the VCW of "aPPle", "jUhUA" is the VCW of "Juhua".
Give you some words; your task is to get the "Vowel-Counting-Word" of each word.

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

4
XYz
application
qwcvb
aeioOa

Sample Output

xyz
ApplIcAtIOn
qwcvb
AEIOOA

两点需要注意：

1.bool函数一定要true和false都要返回，而不要只返回其中之一，否则很容易出错；

2.读入的一点技巧<img src="https://img-blog.youkuaiyun.com/20140914211803562?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQveWFuZ196b25nanVu/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" alt="" />这里在读入数字之后一定要用getchar()函数读掉其后的空格或回车，在读入一行字符串，否则出错！
