Efficient Top-Down Updating of Red-Black Trees

WebThe red-black tree is an especially flexible and efficient form of binary search tree. In this note we show that an insertion or deletion in a red-black tree can be performed in one top-down pass, requiring O (1) rotations and color changes in the amortized case. WebThe other thing we'll probably do with our red-black tree is delete things from it. The first thing is to find the node to delete. This is the same as any BST. Next, we'll want to move the element to delete down to a node that's easier to get rid of. Just as with BSTs, we'll find the left-most right descendant and swap contents. oreillys carthage ms
