Lecture 17 Red-Black Trees

Lecture 17 Red-Black Trees. Slides taken from lectures by Prof. Naveen Garg. 2 - 4 Tree. insert, search, and delete of O(log n) but nodes are dynamic with 2-4 keys. Can we have benefits of 2-4 trees with simple binary nodes?. Lets convert 2-4 tree to a binary tree!.

Red Black Trees

Red Black Trees. Colored Nodes Definition Binary search tree. Each node is colored red or black. Root and all external nodes are black. No root-to-external-node path has two consecutive red nodes. All root-to-external-node paths have the same number of black nodes. Red Black Trees.

Lecture 10 Algorithm Analysis

Lecture 10 Algorithm Analysis. Arne Kutzner Hanyang University / Seoul Korea. Red-Black Trees. General Definition. A red-black tree is a binary search tree + 1 bit per node: an attribute color , which is either red or black. All leaves are empty (nil) and colored black.

Red Black Trees

Red Black Trees. Top-Down Deletion. Recall the rules for BST deletion. If node to be deleted is a leaf, just delete it. If node to be deleted has just one child, replace it with that child

m -ary Trees

m -ary Trees. m -ary trees. Some trees need to be searched efficiently, but have more than two children parse trees game trees genealogical trees, etc. DISADVANTAGE: different directions that a search path may follow (rather than 2: left if less, right if greater) ADVANTAGE:

Binary Search Trees

Binary Search Trees. Implementing Balancing Operations AVL Trees Red/Black Trees Reading: 11.5-11.6. Implementing Balancing Operations. Knowing rotations, we must know how to detect that the tree needs to be rebalanced and which way There are 2 ways for tree to become unbalanced
