title: When Inorder traversing a tree resulted E A C K F H D B G, what would be the preorder equivalent?
body: <p>I am having trouble drawing this tree because I do not know when to put a value to right or left of a tree because it consists of letters.</p>
  
  <p>How do I determine this?</p>
  
  <p><strong>Edited to add:</strong>
  I am given the following choices as possible preorder traversals:</p>
  
  <pre><code>A.  F A E K C D B H G
  B.  F A E K C D H G B
  C.  E A F K H D C B G
  D.  F E A K D C H B G 
  </code></pre>
