WebDec 4, 2024 · Given this, we can define the condition for red-black colorability recursively like so: A binary tree can be colored as a red-black tree with black-height X if and only if: it is null and X==0; OR. both of its children can be colored as red-black trees or red-rooted trees with black-height X-1. A binary tree can be colored as a red-rooted tree ... Weba red-black tree. The important idea behind all of these trees is that the insertand deleteoperations may restructurethe tree to keep it balanced. So lookup, insert, and deletewill always be logarithmic in the number of nodes but insertand deletemay be more complicated than for binary search trees.

More seriously, WebFigure 13.1(a) shows an example of a red-black tree. As a matter of convenience in dealing with boundary conditions in red-black tree code, we use a single sentinel to represent NIL(see page 238). For a red-black tree T, the sentinel T:nil is an object with the same attributes as an ordinary node in the tree.
