WebApr 29, 2024 · 3 Answers Sorted by: 4 You can merge two red-black trees in time O (m log (n/m + 1)) where n and m are the input sizes and, WLOG, m ≤ n. Notice that this bound is tighter than O (m+n). Here's some intuition: When the two trees are similar in size (m ≈ n), the bound is approximately O (m) = O (n) = O (n + m). 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.
