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.util.ArrayList;
import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		
		ArrayList<Integer> list = new ArrayList<Integer>();
		int inNum = 0;
		int count = 0;
		Scanner sc = new Scanner(System.in);	
		do {
			inNum = sc.nextInt();
			if (inNum < 0 || inNum > 10000) {
				System.err.println("Err!");
				return;
			}
			list.add(new Integer(inNum));
			count++;
			// 0が入力されたかデータセットが１万件に達したら入力終了
		 } while (inNum != 0 || count == 10000);
		 
		 for (int i = 1; i < list.size(); i++) {
		 	System.out.printf("Case " + i + ": " + list.get(i-1) + "%n");
		 }
		
	}
