What is a Red-Black Tree?. Other than being a Binary Search Tree it has these specialcoloring properties:. 1. Every node is colored either red or black.2. The root is always black.3. If a node is red, its children must be black.4. Every path from a node to a null reference must containthe same number of black nodes..

Red Black Tree Essentials

Red Black Tree Essentials. Notes from “Introduction to Algorithms”, Cormen et al. . Definition. Red Black Trees A red-black tree is a binary search tree with an extra bit of storage per node. The extra bit represents the color of the node. It's either red or black.

Red-Black Trees

Red-Black Trees. Definitions and Bottom-Up Insertion. Red-Black Trees. Definition: A red-black tree is a binary search tree in which: Every node is colored either Red or Black. Each NULL pointer is considered to be a Black “node”. If a node is Red, then both of its children are Black.

Analysis of Red-Black Tree

Analysis of Red-Black Tree. Because of the rules of the Red-Black tree, its height is at most 2log(N + 1). Meaning that it is a balanced tree. Time Analysis:. 1. Finding any node will take O(log N) time. 2. Inserting any node will take O(log N) time.

red -black tree. Lai Ah Fur. Background: AVL trees may require many restructure operations (rotations) to be performed after an element removal, (2,4) trees may require many fusing or split operations to be performed after either an insertion or removal.
