title: Converting One Binary Tree into another with tree rotation
body: <p>Given are two random binary trees. I need to find a sequence of rotations, so that tree one equals tree two after i am done with them.</p>
  <h2>For instance:</h2>
  <ul>
  <li>Tree one has 0 as root, 1 as a left and 2 as a right child</li>
  <li>Tree two has 1 as root, its right child is 0, zeros right child is 2</li>
  <li>Output: Rotate right around node 0.</li>
  </ul>
  <p>How do I do that for random binary trees?</p>
