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)

'use strict';
function Main(stdin) {
  var line = stdin.split('\n');
  var result = (function(data) {
  	var tmp = [];
  	var index = 0;
		while (data[index] != '0') {
			tmp.push('Case ' + (index + 1) + ': ' + data[index++]);
		}
    return tmp.join('\n');
  }(
    line.map(Number)
  ));
  console.log(result);
}

Main(require('fs').readFileSync('/dev/stdin', 'utf8'));
