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.util.Scanner;
public class Main {

	public static void main(String[] args) {
		
Scanner sc=new Scanner(System.in);
long dd[]=new long[10000];
int x=9;
int r = 0;
long su;
for(int i=0;x==9;i++){
su=sc.nextInt();
if(su!=0){
	dd[i]=su;
}
if(su==0){
	r=i;
	break;
}
}
for(int y=0;y<r;y++){
	int l=y+1;
	System.out.println("Case "+ l +" "+dd[y]);
}


	}

}
