title: How .* (dot star) works?
body: <p>I already understand that <code>.*</code> means zero or more of any character, but
  Could someone explain how <code>.*</code> in the following work and what it would match?</p>
  
  <pre><code>.*([a-m/]*).*
  
  .*([a-m/]+).*
  
  .*?([a-m/]*).*
  </code></pre>
