Create a command line program that will take an internet domain name (i.e. “jana.com”) and print out a list of the email addresses that were found on that website only.
The following is expected output from jana.com and web.mit.edu, but it should also run on other websites. In the example of jana.com, the program should not crawl other subdomains (blog.jana.com, technology.jana.com).
# These are expected output from www.jana.com
