title: Finite Automata Definition of language
body: <p>Hi I am trying to define a language accepted by an FA in simple terms the FA is:</p>
  
  <blockquote>
    <p><img src="https://i.stack.imgur.com/A0sy3.png" alt="s"></p>
  </blockquote>
  
  <p>I think it is the language with strings</p>
  
  <p>(not starting with ab and
  not having substring bb and also ending with an a)
  and also the NULL string</p>
  
  <p>But I do not know if this is the shortest definition or correct at all?</p>
