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)

var saveup = function(x)
{
if(typeof x === "undefined")
{
console.log("x???undefined!!!!");
return a;
}

var a = x;
var f = function(x)
{
a = a + x;
return a;
};
return f;
};


var inputMode = function(x)
{
var count = 0;
process.stdin.resume;
process.stdin.setEncoding("utf-8");
process.stdin.on("data",function(chunk)
{
//if(chunk != 0)
//{
//strs(chunk);
//}
//else
//{
strs(chunk).split("\n").map(Number).filter(function(e){return e != 0 }).forEach(function(e)
{
count = count + 1;
console.log("Case " + count + ": " + e);
})
//}
});
}

var strs = saveup("");
inputMode();
