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

2
44 38 49
25 56 3

Sample Output

Impossible
2575

做这题目简直浪费时间

#include<iostream>
using namespace std;
int main()
{
	int n,a,b,c,i;
	cin>>n;
	while(n--)
	{
		cin>>a>>b>>c;
		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;
	}
	return 0;
}
