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)

'use strict';
process.stdin.on('data', function(chunk) {
  var lines = chunk.toString().split('\n');
  var result = (function(data) {
    return data.filter(function(v){
      return v !== 0 && v.length > 0;
    })
    .map(function(v,i) {
      return 'Case ' + (i + 1) + ': ' + v;
    }).join('\n');
  }(lines.map(Number)
  ));

  console.log(result);
});

process.stdin.resume();
process.stdin.setEncoding('utf8');
