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.Scanner;
public class Main{
    public static void main(String[] args){
        int Array[] = new int[10002];
        Scanner InData = new Scanner(System.in);
        for(int n = 1;n<10002; n++){
            Array[n] = InData.nextInt();
            if(Array[n]==0)
                break;
        }
        for(int n = 1; n<10002; n++){
            if(Array[n]!=0)
                System.out.println("Case "+"n"+": "+Array[n]);
            else
                break;

        }

    }
