Print Test Cases
In an online judge system, a judge file may includes 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.
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.
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.
1 ≤ x ≤ 10000
The number of datasets ≤ 10000
