WebJan 18, 2007 · Red-black trees are similar to AVL trees, but provide faster real-time bounded worst case performance for insertion and deletion (at most two rotations and three rotations, respectively, to balance the tree), with slightly slower (but still O (log n)) lookup time. To quote Linux Weekly News: WebCFS Usage of Red-Black Tree As we know, a red-black tree is a self-balancing binary search tree having nodes colored as red or black. These red and black colors are used to ensure that the tree maintains its balanced nature both during insertions and deletions. Note: Insertion and deletion time complexity of RB Tree is O (log (n)). in this order of ideas

"WebMar 20, 2024 · A red-black tree is essentially a different representation of a 2-3 tree. Let’s dive directly into an example: The tree in (a) shows a 2-3 tree as we’ve seen it in the previous section. We have marked the 3-nodes in red, which leads us directly to a red-black tree. We split every 3-node into two 2-nodes and mark the link between the two in red. " - Red black tree cfs
