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: Wrong Answer)

process.stdin.resume();
process.stdin.setEncoding('utf8');
// ????????????????????????
var x = '';
process.stdin.on('data', function (input) {
    x += input;
});

//???????????????????????????????????£???????????????????§???????
process.stdin.on('end', function () {
    var xArray = x.split('\n');
    //?????????????????´??°???????????????
    var xNumArray = xArray.map(function (n) {
        return parseInt(n);
    })
    //??´??°????????????????????????????????¨???
    for (var i = 0; i < xNumArray.length; i++) {
        var order = 'Case ' + i + ': ';
        console.log(order + xNumArray[i]);

        //??¬????????\??????????????????0?????´?????????
        if (xNumArray[i] === 0) {
            return
        }
    }
})
