WebRed Black Trees asre binary search trees where all nodes in the tree have an extra property: color. The nodes can be either red, black, or (occasionally) double black. The trees have the following properties: Root is black All the external nodes are dummy nodes with no elements, and they are colored black. Red–black trees offer worst-case guarantees for insertion time, deletion time, and search time. Not only does this make them valuable in time-sensitive applications such as real-time applications, but it makes them valuable building blocks in other data structures that provide worst-case guarantees; for example, many data structures used in computational geometry can be based on red–black trees, and the Completely Fair Scheduler used in current Linux kernels and epoll system … fiona cherbak
