#An email address such as "John.Smith@example.com" is made up of a local part ("John.Smith"), an "@" symbol, then a domain part ("example.com").

#The domain name part of an email address may only consist of letters, digits, hyphens and dots.
#The local part, however, also allows a lot of different special characters. 
#Here you can look at several examples of correct and incorrect email addresses.

#Given a valid email address, find its domain part.
