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.Scanner;

public class Main {
	public static void main(String args[]) throws IOException {
		//BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		Scanner scan = new Scanner(System.in);
		StringBuilder sb = new StringBuilder();


		
		int i,s;
		i = 0;

		while(true){
			i++;
			s = scan.nextInt();
			//s = Integer.parseInt(br.readLine());
			if(s == 0){break;}
			
			//str = str+ "Case " + Integer.toString(i) + ": " + str + "\n";
			
			sb.append("Case ");
			sb.append(Integer.toString(i));
			sb.append(": ");
			sb.append(Integer.toString(s));
			sb.append("\n");
			
			
			
		}

		System.out.print(new String(sb));
