Property of red black tree
WebRed-black trees are a fairly simple and very efficient data structure for maintaining a balanced binary tree. The idea is to strengthen the representation invariant so a tree has height logarithmic in 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 ... WebOct 31, 2024 · A red-black tree is a binary search tree with the following properties: Every node is colored with either red or black. All leaf (nil) nodes are colored with black; if a node’s child is missing then we will assume that it has a nil child in that place and this nil child is always colored black. Both children of a red node must be black nodes.
