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 line, i_zero, i, j, util;

line = require('fs').readFileSync('/dev/stdin', 'ascii').split("\n");
i_zero = line.lastIndexOf('0');
line = line.slice(0, i_zero);
util = require('util');
j = 1;
for (i in line) {
	line[i] = util.format("Case %d: %s", j, line[i]);
	j++;
}
console.log(line.join("\n").trim());
