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

public class Main {

	public static void main(String[] args) {
		try(Scanner sc = new Scanner(System.in)){

			List<Integer> lst = new ArrayList<Integer>();
			int input;
			int cnt=0;
			while((input = sc.nextInt())!=0 && cnt < 10000) {
				if(input>=0 && input <=10000){
					lst.add(input);
					cnt++;
				}
			}
			Integer[] aaa = lst.toArray(new Integer[0]);
			int[] ary = new int[lst.size()];
			for(int i = 0; i<lst.size(); i++) {
				ary[i] = aaa[i];
			}
			
			for(int i=0; i< ary.length ; i++) {
				System.out.println(String.format("Case%d: %d",i+1,ary[i]));
