You are validating user input by using JavaScript and regular expressions.
A group of predefined regular expressions will validate two input fields:
An email address in a function named validateEmail (for example, firstname@contoso.com)
A nine-digit number that allows optional hyphens after the second and fifth character in a function
named validateSSN(for example, 555555555 or 555-55-5555)
You need to use the correct expression to validate the input.
Which expression should you insert into each function? (To answer, drag the appropriate regular
expression statement to the correct location. Each regular expression statement may be used once,
more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

HOTSPOT
You are developing a web application that retrieves data from a web service. The data being
retrieved is a custom binary datatype named bint. The data can also be represented in XML.
Two existing methods named parseXml() and parseBint() are defined on the page.
The application must:
Retrieve and parse data from the web service using binary format if possible
Retrieve and parse the data from the web service using XML when binary format is not possible
You need to develop the application to meet the requirements.
