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)

using System;

class myclass
{
    public static void Main()
    {
        int[] l = new int[10001];
        int x;
        for (int i = 0; ; i++){
            x = Int32.Parse(Console.ReadLine());
            if (x == 0){
                x = i;
                break;
            }
            else
                l[i] = x;
        }
        for (int i = 0; i < x; i++)
        {
            Console.WriteLine("Case "+(i+1)+": "+l[i]);
        }
    }
}
