题目描述

I have a very simple problem for you. Given two number A and B, your job is to calculate the Sum of A + B.

输入描述

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 number, A and B. Notice that the number 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. 

输出描述

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.
