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
Sample Output
字典序：AAAAA<AC
本题：找字典序最小字符串T，其不在S中出现，只包含‘A‘‘C‘
