CSE 2050 Ch 17 - Balanced Binary Search
Trees
running time of a BST depends on... - ANS-height of the tree

A BST with n nodes can have a height of - ANS-n-1

balanced - ANS-the height of the tree is at most some constant times logn

tree rotation - ANS-rotateright and rotate left

ex: rotateright will move a node to be the right child of its left child and will update the
children of the nodes

every method that can change the structure of the tree will return - ANS-the new root of
the resulting subtree

factory - ANS-a method that generates new instances of a class

one way to make sure a tree is balanced - ANS-have the key at each node (x) be the
median of all the keys in the subtree at x

good pivots - ANS-those that lay in the middle half of the list - between n/4 and 3n/4

if the key in each node is a good pivot among the keys in its subtree, - ANS-we can
guarantee an overall height of log(4/3)n

a node x is weight-balanced if: - ANS-len(x) + 1 < 4 * min(len(x.left), len(x.right)) + 1)

how many rotations are required to maintain weight balanced trees - ANS-at most 2

rebalance method - ANS-checks for the balance condition and does the appropriate
rotations

toolight method - ANS-checking if a subtree has enough nodes to be a child of a weight
balanced node

checks if current node is weight balanced and if one or two rotations is required
