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 integer

n 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`.
Input The first line of the input contains an integer

(1≤T≤10) ,which denotes the number of test cases.

For each test case,the single line contains an integer

(1≤n<1010000000) .
Output For each test case,print a positive integer or a string `Uncertain`.
Sample Input

Sample Output

  
  
   
   22 35 Uncertain 
   
    
     
     Hint 
     In the first example,it is optimal to split $ 112 $ into $ 21 $ and $ 1 $,and their sum is $ 21 + 1 = 22 $. In the second example,it is optimal to split $ 233 $ into $ 2 $ and $ 33 $,and their sum is $ 2 + 33 = 35 $. In the third example,it is impossible to split single digit $ 1 $ into two parts. 
   
   
    
   
   简单题，先判断是否有两个非零数，然后就是取一个最小的出来加进去
