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".

for(i=1000;i<=9999;i++)
if((i%a==0)&&((i+1)%b==0)&&((i+2)%c==0))
{
cout<<i<<endl;;
break;
}
if(i>9999)
cout<<"Impossible"<<endl;
