In this problem we will explore the problem of how many nodes
are in an AVL tree of height d.
For d = 1,2,3,4 construct an AVL tree of height d with a minimum
number of nodes.
Find an expression for the minimum number of node in an AVL tree of
In this problem you will design a recursive AVL deletion procedure and
execute it on a simple example.
Design a recursive AVL tree deletion procedure. You may assume that
rotation and height calculation procedures are available to you.
Your procedure should be modeled on the deletion procedure of lecture
8, slide 9 and the description of AVL deletion given in lecture 10.
Demonstrate your algorithm by doing all the rotations needed to delete 20
from the following AVL tree. If there is more than one rotation show the result
after each rotation.
