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

Java程式碼不能帶有package語句,主類必須是Main
import java.util.Scanner; import java.math.*; public class Main { public static void main(String args []){ Scanner input=new Scanner(System.in); int T; T=input.nextInt(); for(int i=1;i<=T;i++){ BigInteger a,b; a=input.nextBigInteger(); b=input.nextBigInteger(); if(i!=1) System.out.println(); System.out.println("Case "+i+":"); System.out.println(a+" + "+b+" = "+a.add(b)); } } }
