WebStep 1/6. The upper bound on the height of a binary tree with N keys is O (N), which means the height of the binary tree can't be more than a constant multiple of N. This upper bound can be achieved in the worst-case scenario where the binary tree is skewed to one side. The upper bound on the height of a red-black tree with N keys is O (log N ... WebEven if the tree is filled with red nodes, nb is O (n) because at most, roughly half the tree will be red. [whoa, that's a big handwave] Therefore, the height of a red-black tree is O (log n) .

From the definitions: The number of black nodes from the root to a node is the node's black depth. Let's use d ( n) for the black depth of a node n. So d ( 8) = 1, for example, because one node is black along the path 13 → 8 (namely node 13 ).
