　　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
