Red-Black Trees Red-black trees: Binary search trees augmented with node color Operations designed to guarantee that the height h = O(lg n) First: describe the properties of red-black trees Then: prove that these guarantee h = O(lg n) Finally: describe operations on red-black trees 3. WebA red-black tree with n nodes has height h ≤ 2 lg(n + 1). Proof: Let h be the height of the red-black tree with root x. By Theorem 2, bh(x) ≥ h/2 From Theorem 1, n ≥ 2bh(x) - 1 Therefore …
WebRed-black trees maintain a slightly looser height invariant than AVL trees. Because the height of the red-black tree is slightly larger, lookup will be slower in a red-black tree. …
