Problem:
Print Test Cases

In the online judge system, a judge file may include multiple datasets to check whether the submitted program outputs a correct answer for each test case. This task is to practice solving a problem with multiple datasets.

Write a program which reads an integer x and print it as is. Note that multiple datasets are given for this problem.

Input

The input consists of multiple datasets. Each dataset consists of an integer x in a line.

The input ends with an integer 0. You program should not process (print) for this terminal symbol.

Output

For each dataset, print x in the following format:

Case i: x

where i is the case number which starts with 1. Put a single space between "Case" and i. Also, put a single space between ':' and x.

Constraints

1 ≤ x ≤ 10000

The number of datasets ≤ 10000

Sample Input

3
5
11
7
8
19
0

Sample Output

Case 1: 3
Case 2: 5
Case 3: 11
Case 4: 7
Case 5: 8
Case 6: 19

Solution in C# (judge verdict: Accepted)

        /*---??£?¨???¨---*/

        //0?????\????????§????????????
        while (true){
            list.Add(int.Parse(Console.ReadLine()));
            if(list[i] == 0){
                break;
            }
            i++;
        }

        /*0?????§????????????????????????*/
        for(k = 0; k < i; k++){
            Console.WriteLine("Case {0}: {1}", k+1, list[k]);
        }
    }
