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.

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.
