/*
Cleartrip decided that they wanted to verify the username and password of its users while they were authenticating for a process. One of the code service forms a GET URL which contains the username and password as its parameters. While parsing the URL, the code needs to extract the key-value pairs of ALL the parameters passed in the request URL which may contains '&' or/and '='.

The string can contain any type of alphabetical, numeric and special characters in the URL.

Print the following:
username: From the URL. 
pwd: From the URL.
profile: From the URL.
role: From the URL.
key: From the URL.

Constraints:
1 <= |Length of the URL| <= 100
