WebSep 26, 2013 · BST deletion. Suppose we want to delete a targetted value t from a red-black tree T. Let's consider first the deletion algorithm for a (regular/plain/vanilla) Binary Search Tree: Let n t be the node that stores the targetted key. + if n t has at most one child, delete it, replacing it with either its lone child or a terminal node. + if n t has ... WebTherefore, the height of a red-black tree is O(log n). There is an important correspondence between red-black trees and 2-3-4 trees. A black node and its red children are equivalent to a single node in a 2-3-4 tree. A black node with black children is just a 2 node in a 2-3-4 tree. We will use this correspondence to make sense of things later on. haileyzphotography
