Alice’s younger sister just started to go school. Today she learns addition in her class. But she can’t do it well. Her class teacher gives some assignment. Her teacher gives two integer numbers to add. She tries to add the numbers but sometime she fail in case of some critical numbers and puts ‘?’ marks at those positions.
Now you help Alice’s sister. You just give her the solution where she write down ‘?’ marks and if she done well then write ‘OK’.
Input
The first line of the input contains an integer T (T ≤ 1000) denoting the number of test cases. Each test case contains three lines given A, B and C. A and B is her assignment number and C is Alice’s sister's answer. 0 ≤ A, B ≤ 99999 and C will contain with number and ‘?’.
Output
For each case, print the case number and the number deserve solution.
Sample
Input: 4 123 123 ?46 234 34 ?68 12345 12371 ?4?1? 421 32 453 Output: Case 1: 2 Case 2: 2 Case 3: 276 Case 4: OK

The pattern with problems from Najmuzzaman: if told to read blanklines between cases, don't; if not, do. This is the latter case. |

'?' stands for just a single digit number or it can have multi-digit number also?
