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 … WebPart of the catch is that although standard red-black trees have additional cases to deal with due to 3-nodes that can lean left or right, left-leaning red-black trees have a universal asymmetry between the left and right versions of the algorithms.
