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.io.*;

public class Main{
    public static void main(String []args){
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        try{
            int [] number;
            number = new int[10000];
            for(int i=0;i<10000;i++){
            String line = reader.readLine();
            number[i] =Integer.parseInt(line);
            if(number[i] == 0){
                break;
            } 
            }
            for(int j=1;j<=10000;j++){
                System.out.println("case "+j+": "+number[j-1]);
                if(number[j-1]==0){
                    break;
                }
            }
        }
        catch(IOException e){
            System.out.println(e);
        }
    }
