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 JavaScript (judge verdict: Accepted)

process.stdin.resume();
var x = '';
process.stdin.setEncoding('utf-8');
process.stdin.on('data', function (input) {
    x += input;
});

process.stdin.on('end', function () {
    var xArray = x.split('\n');
    var output = [];
    for(var i = 0; i < xArray.length; i++) {
        if(0 != xArray[i]) {
            output.push('Case ' + (i + 1) + ': ' + xArray[i]);
        }
    }
    console.log(output.join('\n'));
});
