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 = 2222222222222221110
