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: WA: Presentation Error)

#include<iostream>

int main(){
   int x[10001];
   int i = 0;
   while(i <= 10000) {
       std::cin >> x[i];
       if(x[i] == 0) break;
       
       ++i;
       std::cout << std::endl;
   }

    for(int j = 0; j < i; j++) {
        std::cout << "Case " << (j + 1) << ": " << x[j] << std::endl;
    }

    return 0;
   
}
