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.Scanner;
import java.util.ArrayList;

class Main {

	public static void main(String[] args) {
	
		ArrayList<Integer> x = new ArrayList<Integer>();
		int y = 1;
		int i;
		Scanner sc = new Scanner(System.in);
		
		while(true){
			int temp = sc.nextInt();
			if(temp == 0)
				break;
			x.add(temp);
		}
			
		for(i = 0; i < x.size(); i++){	
			
			int val = x.get(i);
			
			System.out.println("Case " + y + ": " + val);
			y++;
		}
		

	}
