An email address such as "[email protected]" 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.

Example

  • For address = "[email protected]", the output should be findEmailDomain(address) = "example.com";

  • For address = "<>[]:,;@"!#$%&*+-/=?^_{}| ~.a"@example.org", the output should be findEmailDomain(address) = "example.org".

Hints

  • lastIndexOf()
  • slice()

Input/Output

  • [execution time limit] 5 seconds (ts)

  • [input] string address

Guaranteed constraints:

10 ≤ address.length ≤ 50.

  • [output] string
