WebJan 14, 2024 · 1. I want to prove any AVL tree can be turnt into a red-black tree by coloring nodes appropriately. Let h be the height of a subtree of an AVL tree. It is given that such a coloring is constrained by these cases: h even black height = h 2 + 1, root node black. h odd black height = h + 1 2, root node red. After that the root node is colored black. WebRed and black tree under the premise of balancing the binary search tree, each node adds a member variable of _color, which is used to mark each node. Next, we'll analyze the insertion algorithm for red and black trees. An AVL tree needs to meet the following requirements. 1. Every knot, not black or red. 2. The root node of the tree must be black
