and None). Now when I start checking these checkboxes, it should not let me check more than
3 checkboxes. When I try to check on 4th checkbox it should alert me as "Only 3 days can be
selected. You have already selected sunday, monday and tuesday". Now when I click on None,
all other checkboxes should be deselected. Also when 'None' is selected and I select any other

Create a simple form with a text field and a submit button. When I enter a URL in this text field
and submit the form, it should alert me the domain name from the entered url. For example, If I
enter:

1. http://example.com/folder/file.html​ , then on submitting the form it should alert
   something like:
   ○ Domain: example.com.
2. With subdomain: ​ http://vinsol.example.com/folder/file.html​ , then on submitting the
   form it should alert something like:
   ○ Domain: example.com
   Subdomain: vinsol.
   Basic Idea is to extract domain name and subdomain from a URL.
