Problem Description

As a former ACMer, "AC" is a special abbreviated word which can bring much pleasure to me. Sometimes it means everything.

This problem is about "AC".

One day, I write a long string S on the paper which contains "A" and "C". Now I want to find a lexicographic minimum string T satisfied that T is distinct with all substring of S.

Input

The first line of input file contains an integer T indicating the number of case.

In each test case:

Input a string S consist of "A" and "C". The length of S is not large than 100.

Output

For each test case:

You should output the string T meet the condition.

Sample Input

1

ACAC

Sample Output

AA

题意是要输出最小的字典序。且不是原字符串的的子串。。找到最长连续A子串。

。

由于要不属于原字符串所以再在其后加一A就可以。

在给些数据吧。

AACAAA

ACACA

CCCAA

AAAA

AAA
