Validate the domain

Given a webpage domain like www.profound.academy or google.com or www.brilliant.org, your task is to validate it. Make sure that the domain is actually written correctly. The rules of a domain name:
  • It can start with www or it can have nothing in the beginning
  • It should have a name that only has Latin letters (like profound or google)
  • It should end with any of com, org, or academy
The input contains a single string - the domain.
The program should print Valid in case the domain is valid and Invalid in case it isn’t.
