Description
Given two integers A and B, your job is to calculate the Sum of A + B.
Format
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. You may assume the length of each integer will not exceed 2000.
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.
