Use regular expressions to determine the validity (just return true/false, you dont need to write the reason why or print anything, etc.). The requirements are:

1. The email should start with one or more characters other than @

2. Then it should have the @ sign

3. After the @ should come the website meaning some letters or numbers, then the dot . symbol, and then some more letters or numbers.
