To everyone in CS 362 -

In the code I gave you for the AVL tree rotation, at the end of the
singleRight function you will find this comment and code:
	   // adjust changed heights for subtrees
	   resetHeight(p);

For the double rotations, more than one subtree has changed its height.
Several of the poeple who have turned this in have trees with
incorrect heights. 

Try this input to reveal the problem at the node containing c: ptywvcf

Also, you can use the following sequence of characters to get all the
rotations in one test: psvdmyxcbhfmyob

Remember that ~katz362/support/avlrun is an oracle. It will display 
the correct answer if you give it some input. Its answers don't label
the parent, inner child, and outer child.
