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.
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.

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

感觉用java 做大数相加的这个题好简单呀
