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 JAVA (judge verdict: Accepted)

import java.io.*;
import java.util.Scanner;

class Main
{
	public static void main (String[] args) throws IOException
	{
  		Scanner in = new Scanner(System.in);

		for(int i = 1; i > 0; i++){

	      	String X;
	  		int x;
	
	  		X = in.nextLine();
	  		x = Integer.parseInt(X);
	
	      	if(x == 0){
	        	break;
	      	}else{
		  		System.out.println("Case " + i + ": " + x);
      		}
    	}
	}
}
