WebFeb 23, 2024 · Red Black is a kind of balanced binary search tree. Unlike regular binary search trees (BST), the speed of an RBT remains relatively consistent no matter the height of the tree, due to its self-balancing property. This attribute is achieved through a set of limitations placed on the depth and color of each node in the tree. Properties of RBT WebIn a red-black tree, there are two operations that can change the structure of the tree, insert and delete. These changes might involve the addition or subtraction of nodes, the changing of a node's color, or the re-organization of nodes via a rotation.
