题目描述

A string is perfect if it has the smallest lexicographical ordering among its cyclic rotations.
For example: "0101" is perfect as it is the smallest string among ("0101", "1010", "0101", "1010").

Given a 01 string, you need to split it into the least parts and all parts are perfect.

输入描述:

The first line of the input gives the number of test cases, T (T≤300)T\ (T \leq 300)T (T≤300).  test cases follow.

For each test case, the only line contains one non-empty 01 string. The length of string is not exceed 200.

输出描述:

For each test case, output one string separated by a space.
