Looking at writing a simple Apex trigger to update a lead or contact field based on a task being added.

Have written an after insert Task trigger.  Quick question...

What is the best way to determine if the WhatID references a lead or contact?  Can the ID field be treated as a string and what are the ID prefixes for the Lead and Contact table?

Thanks!
