title: Balancing a Binary Tree (AVL)
body: <p>Ok, this is another one in the theory realm for the CS guys around.</p>
  
  <p>In the 90's I did fairly well in implementing BST's. The only thing I could never get my head around was the intricacy of the algorithm to balance a Binary Tree (AVL).</p>
  
  <p>Can you guys help me on this?</p>
