title: confusion in finding first and follow in left recursive grammar
body: <p>Recently I  faced the problem for finding first and follow </p>
  
  <pre><code>S-&gt;cAd
  A-&gt;Ab|a
  </code></pre>
  
  <p>Here I am confused with first of A
  which one is correct {a} , {empty,a} as there is left recursion in A's production  .
  I am confused whether to include empty string in first of A or not 
  Any help would be appreciated.
  -------------edited---------------</p>
  
  <p>what wil be the first and follow  of this ,,This is so confusing grammar i have ever seen</p>
  
  <pre><code>S-&gt;SA|A
  A-&gt;a
  </code></pre>
  
  <p>I need to prove this grammar is not in LL(1) using parsing table but unable to do because i didnot get 2 entry in single cell.</p>
