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 Python3 (judge verdict: Wrong Answer)

def main():
    data = []
    while 1:
        n = input().split()
        ans = int(n[0])
        data.append(ans)

        if ans == 0:
            break

    length = len(data)
    what_large = length > 10000

    if what_large:
        print("Too Large")
    else:
        for i in range(len(data)):
            d_val = data[i]

            if d_val != 0:
                print("Case {0}: {1}".format(i+1,d_val))
            else:
                break

if __name__ == '__main__':
    main()
