杭电1002 A + B Problem II

java还是有好处的，有封装就是任性，不符来辩

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

import java.math.BigInteger;
import java.util.Scanner;

public class Main {

public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int num = in.nextInt();
for(int i = 1;i<=num;i++){
BigInteger a = in.nextBigInteger();
BigInteger b = in.nextBigInteger();
System.out.println("Case "+i+":");
System.out.println(a+" + "+b+" = "+a.add(b));
if(i != num)
System.out.println();
}
}
}
