Problem Description
There is once a king and queen, rulers of an unnamed city, who have three daughters of conspicuous beauty.
The youngest and most beautiful is Psyche, whose admirers, neglecting the proper worship of the love goddess Venus, instead pray and make offerings to her. Her father, the king, is desperate to know about her destiny, so he comes to the Delphi Temple to ask for an oracle.
The oracle is an integern without leading zeroes.
To get the meaning, he needs to rearrange the digits and split the number into <b>two positive integers without leading zeroes</b>, and their sum should be as large as possible.
Help him to work out the maximum sum. It might be impossible to do that. If so, print `Uncertain`.

The oracle is an integer
To get the meaning, he needs to rearrange the digits and split the number into <b>two positive integers without leading zeroes</b>, and their sum should be as large as possible.
Help him to work out the maximum sum. It might be impossible to do that. If so, print `Uncertain`.
Input
The first line of the input contains an integer T (1≤T≤10) , which denotes the number of test cases.
For each test case, the single line contains an integern (1≤n<1010000000) .
For each test case, the single line contains an integer
Output
For each test case, print a positive integer or a string `Uncertain`.
Sample Input
31122331
Sample Output
