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
枚举就可以了。。
代码语言：javascript复制import java.util.Scanner;
public class Main{
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int t = sc.nextInt();
while (t-- > 0) {
int a = sc.nextInt();
int b = sc.nextInt();
int c = sc.nextInt();
boolean is = true;
int tm=a;
while(a<1000){
a=a tm;
}
//注意！答案的范围是[1000,9999]
for (int i = a; i < 10000; i = i tm) {
//此处注意i是加tm，而不是再加a了，因为a可能变了。
if ((i 1)%b==0&&(i 2)%c==0) {
System.out.println(i);
is = false;
break;
}
}
if (is) {
System.out.println("Impossible");
}
}
}
}
