源代码：

import java.math.BigInteger; import java.util.Scanner; public class Main{ public static void main(String[] args) { int t; Scanner scanner=new Scanner(System.in); t=scanner.nextInt(); for (int i = 1; i <=t; i++) { String str1,str2; BigInteger A,B; str1=scanner.next(); str2=scanner.next(); A=new BigInteger(str1); B=new BigInteger(str2); System.out.println("Case "+i+":"); System.out.print(A+" + " +B +" = " ); System.out.println(A.add(B)); if(i!=t){ System.out.println(); } } } }
