Basically what im trying to do is use a stack to keep track of the
items in the AVL tree so that rotations will go smoothly. Having
problems with the stack getting initialized and actually storing the
data there. So that i can reference the elements stack[-3].left =
stack[-2].right and so on for balancing.
thanks
