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;
import java.util.LinkedList;

class Main{
    public static void main(String[] args){
        Scanner sc = new Scanner(System.in);
        LinkedList<Integer> l = new LinkedList<Integer>();
        while(sc.hasNext()){
            int j=sc.nextInt();
            if(j==0){
                break;
            }
            l.add(j);
        }
        int n=0;
        for(int i=0; i<l.size(); i++){
            if(l.get(i)<1 || 10000<l.get(i)){
                n++;
            }
        }
        if(l.size()>9999){
            System.out.println("Too Large");
        }else if(n!=0){
            System.out.println("There is an incorrect number.");
        }else{
            int k=0;
            for(int i=0; i<l.size(); i++){
                k++;
                System.out.println("case "+k+": "+l.get(i));
            }
        }
    }
