WebRed Black Trees asre binary search trees where all nodes in the tree have an extra property: color. The nodes can be either red, black, or (occasionally) double black. The trees have the following properties: Root is black All the external nodes are dummy nodes with no elements, and they are colored black. WebColor Flip Now we consider the color flip operation that is essential to LLRB tree implementation. Given a node, this operation simply flips the color of itself, and the left and right children. However simple it may look now, we will examine its consequences later on. For now, take a look at the implementation provided in RedBlackTree.java.
