Problem Q: Server

Input: server.in
Output: server.out

Users of computers frequently enter URLs (Uniform Resource Locators) in the form

    protocol://server.network

For example, in the URL

    http://www.monkey.donkey.zebra.com

the protocol is "http", the server is "www", and the network is "monkey.donkey.zebra.com". For purposes of this problem, the protocol and server are alphanumeric strings, whereas the network is an alphanumeric string that may also contain periods (however, the URL cannot end with a period or contain two consecutive periods).

Input

Each line of the input contains a URL in the format specified above. No line will be longer than 80 characters. The input is terminated by end-of-file.

Output

Each line of input will give rise to one line of output, consisting of the word "server", followed by a colon and one blank space, and the server from the corresponding line of input.

Sample input

http://www.monkey.donkey.zebra.com
ftp://newton.cs.colorado.edu

Output for sample input

server: www
server: newton
