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;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication2
{
    class Program
    { 
        static void Main(string[] args)
        {
            //string[] s =Console.ReadLine().Split(',');

            //int w = int.Parse(s[0]);
            List<string> stringList = new List<string>();
            int count=1;

            for (int i = 0; ; i++)
            {
                string x = Console.ReadLine();
                if (x == "0")  break;
                stringList.Add(x);
            }

            foreach(string j in stringList){
                Console.WriteLine("Case "+count+": "+j);
                count++;
            }
            //int n =int.Parse(s);
        }
