Problem Description

Happy new year to everybody!
Now, I want you to guess a minimum number x betwwn 1000 and 9999 to let
(1) x % a = 0;
(2) (x+1) % b = 0;
(3) (x+2) % c = 0;
and a, b, c are integers between 1 and 100.
Given a,b,c, tell me what is the number of x ?

 

Input

The number of test cases c is in the first line of input, then c test cases followed.every test contains three integers a, b, c.

 

Output

For each test case your program should output one line with the minimal number x, you should remember that x is between 1000 and 9999. If there is no answer for x, output "Impossible".

 

Sample Input

244 38 4925 56 3

 

Sample Output

Impossible2575
