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.io.BufferedReader;
import java.io.InputStreamReader;
class Main{
    public static void main(String[] args) throws Exception {
        int num;
        int[] x = new int[10001];
        int a = 1;
        int i = 0;
        int c = 0;
        int d =0;
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));    
        for (i=0;a!=0;i++) {
            x[i] = Integer.parseInt(br.readLine());
            a = x[i];
        }
        i--;
        while(i!=0){
            c++;
            System.out.println("Case "+c+": "+x[d]);
            d++;
            i--;
        }
    }
}
