Property. WebA red-black tree (RBT) is a balanced version of a Binary Search Tree guaranteeing that the basic operations (search, predecessor, successor, minimum, maximum, insert and delete) have a logarithmic worst case performance. Binary search trees (BSTs) have the disadvantage that they can become unbalanced after some insert or delete operations. WebA red-black tree is a type of binary search tree.
