Each node of the binary tree has an extra bit, and that bit is often interpreted as the color (red or black) of the node. These color bits are used to ensure the tree remains approximately balanced during insertions and deletions.

WebA red-black tree is a type of binary search tree. It is self balancing like the AVL tree, though it uses different properties to maintain the invariant of being balanced. Balanced binary search trees are much more efficient at search than unbalanced binary search trees, so the complexity needed to maintain balance is often worth it. They are called red-black trees … WebCase 1: T is empty. If T is empty, we make K the root of the tree and color it black. Case 2: P is black. If K ’s parent node P is black, it can not violate any of the properties. Therefore, in this case, we do not need to do anything. …
