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.
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.
You should output the string T meet the condition.
Sample Input
1 ACAC
Sample Output
AA
大致意思就是,找出最长连续的A的数目num然后再输出num+1个A,题目我是没看出来有说这个东西。只是看队友A了问了才知道的,希望ACdream以后出题能考虑到这点吧
