WebMar 19, 2024 · The basic idea behind red-black BSTs is to encode 2-3 trees by starting with standard BSTs (which are made up of 2-nodes) and adding extra information to encode 3-nodes. We think of the links as being of two different types: red links, which bind together two 2-nodes to represent 3-nodes, and black links, which bind together the 2-3 tree. WebMar 23, 2024 · A red-black tree is one type of binary search tree that satisfies the following properties: Every node is either red or black. The root is black. Every leaf (nil) is black. If a parent node is red, then both of its children are black. All simple paths from the node to descendant leaves contain the same number of black nodes for each node. 2).
