A+B Problem II BufferedInputStream問題

A+B Problem II

不知道是不是我很久沒刷oj的問題，代碼總是通不過，顯示presentationerror。找了很多遍才發現是忘寫了BufferedInputStream以及下面空行的判斷條件，不知道是不是系統過于嚴苛了，不過這樣确實嚴謹的，希望大家引以為戒吧！

下面是我的代碼：

import java.io.*;  

import java.math.*;  

import java.util.*;  

import java.text.*;

public class Main {

    public static void main(String[] args) {

        // TODO Auto-generated method stub

        Scanner in = new Scanner(new BufferedInputStream(System.in));

        int n,k=1;

        n=in.nextInt();

        while(n!=0) {                

            BigInteger a,b;                

            a = in.nextBigInteger();                

            b = in.nextBigInteger();                            

            System.out.println("Case "+ k++ +":");                

            System.out.println(a+" + " +b+" = "+a.add(b));                

            if(n!=1)System.out.println();                

            n--;            

        }

        in.close();

    }

}

Problem Description I have a very simple problem for you. Given two integers A and B, your job is to calculate the Sum of A + B.  

Input The first line of the input contains an integer T(1<=T<=20) which means the number of test cases. Then T lines follow, each line consists of two positive integers, A and B. Notice that the integers are very large, that means you should not process them by using 32-bit integer. You may assume the length of each integer will not exceed 1000.  

Output For each test case, you should output two lines. The first line is "Case #:", # means the number of the test case. The second line is the an equation "A + B = Sum", Sum means the result of A + B. Note there are some spaces int the equation. Output a blank line between two test cases.  

Sample Input

2 1 2 112233445566778899 998877665544332211  

Sample Output

Case 1: 1 + 2 = 3 Case 2: 112233445566778899 + 998877665544332211 = 1111111111111111110
