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.*;

//Circle in a Rectangle
public class Main {
	public static void main(String args[])
	{
		String str;
		int[] output = new int[10000];
		Scanner sc = new Scanner(System.in);
		str = sc.nextLine();
		int i = 0;
		while(Integer.parseInt(str) != 0)
		{
			output[i] = Integer.parseInt(str);
			str = sc.nextLine();
			i++;
		}
		int n = 0;
		for(n = 0;n<i;n++)
		{
			System.out.println("Case " + (n+1) + ": " + output[n]);
		}
		sc.close();
	}
}
