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: Wrong Answer)

using System;
using System.Text;

namespace AOJ_Hello_World {
	class Program {
		static void Main (string[] args) {
			int counter = 0;
			while (true) {
				long input=getInputs(1)[0];
				if (input == 0)
					break;
				Console.WriteLine("Case {0} :{1}",counter++,input);
			}
		}

		private static long[] getInputs (long length){
			var sab = Console.ReadLine();
			long[] a = new long[length];
			for (int i = 0;i < length;i++) {
				a[i] = long.Parse(sab.Split(' ')[i]);
			}
			return a;
		}
	}
