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: Wrong Answer)

import java.util.*;
 
 class Main{
 	  public static void main(String[] args) {
 	  	
 	  	Scanner str = new Scanner(System.in);
 	  	ArrayList<String> note = new ArrayList<String>();
 	  	
	 	  	while(str.hasNext()){
	 	  		
	 	  		String s = str.next();
	 	  		if(s.indexOf("0") > 0 || s.startsWith("0")){ 	  			
	 	  			break;
	 	  		}else{
	 	  			note.add(s); 	  			
	 	  		}
	 	  		
	 	  	}
 	  	
 	  	for(int i = 0; i < note.size(); i++){
 	  			System.out.println("Case " + (i+1) + "; " +  note.get(i));
 	  	}
 	  }
 }
