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) {
		Scanner sc = new Scanner(System.in);
		/*
		int i = 1;
		int x;

		while (true) {

			x = sc.nextInt();
			System.out.println("Case " + i + ":" + x);
			i++;
			if (x == 0) {
				break;
			}
		}

		*/

		StringBuilder sb = new StringBuilder();
		String n;
		String a = "Case ";
		String b = ": ";
		for(int i = 1;(n = sc.next()).length() != 1 || n.charAt(0) != '0';i++) {
			sb.append(a);
			sb.append(i);
			sb.append(b);
			sb.append(n);
			sb.append('\n');
		}
		System.out.print(sb.toString());
	}
