## 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 test:

Input21 2112233445566778899 998877665544332211OutputCase 1:1 + 2 = 3Case 2:112233445566778899 + 998877665544332211 = 1111111111111111110## Note:
