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)

var input = function(){
  return input= require('fs').readFileSync('/dev/stdin', 'utf8').split("\n").map(Number);
  };

var increment = function(x)
{
  return x+1;
}

var out = function(counter,x)
{
  console.log("Case " + increment(counter) + ": " + x );
  return x;
}

var Arr=input()
.forEach(function(element,index)
{
  if (element != 0)
  {
    out(index,element);
  }
}
);
