title: (Homework) Converting an NFA to a DFA with an epsilon transition, but no transition for some a in the alphabet
body: <p>If my alphabet is {a,b} and my nfa has the following transitions:</p>
  
  <pre><code>State    |      a        b        epsilon        
  --------------------------------------------
  q0              q1      null        q1
  q1              q2       q1         none
  q2              q2       q1         none
  </code></pre>
  
  <p>Is this table wrong? should delta(q0, b) = q1 because q0 can move on epsilon to state q1?</p>
