Illustrate that the nodes of any AVL tree T can be
colored "red" and "black" so that T becomes a
red-black tree.

AVL Tree Red-Black Tree
(20:3) (20:b)
/ \ --> / \
(15:2) (30:2) (15:b) (30:b)
/ \ \ / \ \
(10:1) (17:1) (35:1) (10:r) (17:r) (35:r)
* perform pre order traversal
* assign colour of Red/Black node based on height of each AVL node
