2) a) Consider a modified red-black tree which satisfies all the usual conditions for a red-black tree exceptthat the root may be either black or red. Suppose a modified red-black tree T has a red root node. If we recolor the root node black, is the resulting tree a “normal” red-black tree? b) What is the largest and smallest number of nodes in a red-black tree with black-height k?

Part 3: Red-black trees
Left-leaning red-black trees, as they are described in the
Sedgewick and Wayne text, undergo 3 possible transformations as
they grow: rotateLeft, rotateRight, and flipColors. You may refer
to the text or my lecture notes for the details of each of these
tree transformations.

True or False? 1. In a 2-3 tree, the last node that splits is a leaf that already contains two entries. 2. In a red-black tree, a red node cannot have red children. 3. The vertices in a graph may only have one topological order. 4. In a weighted graph, the shortest path between two given vertices has the largest edge-weight sum.

Recall from Assignment 2 the definition of a binary tree data structure: either an empty tree, or a node with two children that are trees. Let T(n) denote the number of binary trees with n nodes.
