HDOJ-1002 A + B Problem II

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

不知道坑了多少人的题目~首先位数1000位long long也存不下，当然java很好做，然而目前没接触过，所以只能用数组存数来计算，然后一个地方要注意：它说每组测试数据 间 有空行隔开，也就是说最后一组数据后是没有空行的。这个没找出来，一直Presentation Error，看了Discuss后才知道自己错哪了。细节啊！！

AC后觉得很Interesting~
