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) {
		// TODO ?????????????????????????????????????????????
		ArrayList<Integer> x = new ArrayList<Integer>();
		int tmp;
		int cnt = 0;
		Scanner sc = new Scanner(System.in);
//		sc.useDelimiter("\\r\\n");

		tmp = sc.nextInt();
		x.add(tmp);
		cnt++;

		while(tmp!=0){
			sc.hasNext();
			tmp = sc.nextInt();
			x.add(tmp);
			cnt++;
		}

		for(int i=0;i<cnt-1;i++){
			System.out.println("Case "+ (i+1) +": "+ x.get(i));
		}
		sc.close();
	}

}
