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.
