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){
		Scanner sc = new Scanner(System.in);
		int[] data = new int[1000000];
		int button = 0;
		int i = 0;
		while(button == 0){
			data[i] = sc.nextInt();
			if(data[i] == 0){
				button = 1;
			}
			i++;
		}
		int j ;
		for(j = 0; j<=i; j++){
			if(data[j] != 0){
				System.out.println("case "+(j+1)+": "+data[j]);
			}
		}
	}
}
