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: Wrong Answer)

import java.io.*;

class Main{
	public static void main(String[] args){
		try{
 			BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
 			StringBuilder sb = new StringBuilder();
 			int i=0;
 			while(true){
 				int data = Integer.parseInt(br.readLine());
 				if(data == 0){
 					break;
 				}
 				else{
 					sb.append("Case ").append(Integer.toString(i++)).append(": ").append(Integer.toString(data)).append("\n");
 				}
 			}
 			System.out.println(sb);
		}
		catch(Exception e){
			System.out.println(e);
		}
	}
}
