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){

		//初期処理
		Scanner sc = null;
		ArrayList<Integer> array = new ArrayList<Integer>();
		int number = 0;
		
		//テキスト入力クラス
		sc = new Scanner(System.in);

		//do~while処理
		do{
			
			//現在の入力値
			number = sc.nextInt();
			//配列に追加
			array.add(number);

		//入力結果が0になるまで入力
		}while(number != 0);
		
		//最後の配列を出力しないので、ループは配列の数より１回少ない
		for(int i =1;i < array.size();i++){
			//配列に格納されている結果を出力
			System.out.println("Case "+i+": "+array.get(i-1));
		}
	}
}
