WebAs a result, the path can only be twice as long as the tree's black depth. Therefore, the worst case height of the tree is O (2 log nb). Even if the tree is completely red, nb is O (n) since only around half of the tree will be red. Therefore, the height of a red-black tree is O (log n). WebRed-Black tree is a self-balancing binary search tree in which each node contains an extra bit for denoting the color of the node, either red or black.

WebRed-black trees are relatively simple balanced binary tree data structure. The idea is to strengthen the representation invariant so a tree has height logarithmic in the number of nodes n. To help enforce the invariant, we color each node of the tree either red or black. Where it matters, we consider the color of an empty tree to be black.

WebNote that the tree is perfectly balanced wrt the black nodes. By property 4 there are ≤h/2 red nodes along a path (not counting the subroot), and hence ≥h/2 black. So a node of height h has black-height ≥h/2. It is straightforward to prove by induction that a red-black tree with n internal nodes (nonleaves) has height h ≤2 log(n+1). spindles ideasWebThe depth of a red-black tree with n keys is no more than 2 lg(n). ...
