Solve: Build Email Address

Created By: Justin Maier

/ Version: 2024.8.0

An email address is composed of two parts: a username and a domain name (e.g. "gmail.com"). A full email address has the form "@".

Write a function buildEmailAddress that takes two String parameters representing a username and a domain name and returns a String representing the email address formed from these parts.

For example, if the username parameter is "abc" and the domain name parameter is "gmail.com", you should return "[email protected]".
