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.io.*;
import java.util.*;

public class Main{
	public static void main(String[] args)throws IOException{
		BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
		List<String> lst=new ArrayList<String>();
		boolean roop=true;
		while(roop){
			String s=br.readLine();
			lst.add(s);
			if(s.equals("0"))roop=false;
		}
		for(int i=0;i<(lst.size()-1);i++){
			System.out.println("Case "+(i+1)+": "+lst.get(i));
		}
