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.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO 自動生成されたメソッド・スタブ
		int Max = 10000;
		int[] x = new int[Max];
		int n = 0; // xの要素数
		Scanner sc = new Scanner(System.in);
		int input = 100;
		boolean inputjudge = true; // 入力要素が範囲内に収まっているかを確認するための変数;

		for (int i = 0; i < x.length; i++) {
			input = sc.nextInt();
			if (input >= 1 && input <= 10000) {
				x[i] = input;
				n++;
			} else if (input == 0) {
				break;
			} else { // 入力された値が範囲外のとき
				inputjudge = false;
				break;
			}
		}

		if (inputjudge == true) {

			for (int i = 0; i < n; i++) {
				System.out.println("Case " + (i + 1) + ": " + x[i]);

			}
		}
	}
