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
		while (sc.hasNext()) {

			// 現在の入力値
			number = sc.nextInt();
			
			//0だったら抜ける
			if (number == 0)
				break;
			// 配列に追加
			array.add(number);

			// 入力結果が0になるまで入力
		}

		// 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 = 0; i < array.size(); i++) {
			// 配列に格納されている結果を出力
			System.out.println("Case " + (i+1) + ": " + array.get(i));
		}
	}
}
