They have the following properties: + 1. The number of black edges on every path from the root to a leaf is + constant. + 2. No two red edges are adjacent. + Therefore there is an upper bound on the length of every path, it's + O(log n) where n is the number of nodes in the tree. No path can be longer + than 1+2*P where P is the length of the shortest path in the tree. + Useful for the implementation: + 3. If one of the children of a node is NULL, then the other one is red + (if it exists). + + In the implementation, not the edges are colored, but the nodes. The color + interpreted as the color of the edge leading to this node. The color is + meaningless for the root node, but we color the root node black for + convenience. All added nodes are red initially. + + Adding to a red/black tree is rather easy. The right place is searched + with a usual binary tree search. Additionally, whenever a node N is + reached that has two red successors, the successors are colored black and + the node itself colored red. This moves red edges up the tree where they + pose less of a problem once we get to really insert the new node. Changing + N's color to red may violate rule 2, however, so rotations may become + necessary to restore the invariants. Adding a new red leaf may violate + the same rule, so afterwards an additional check is run and the tree + possibly rotated. + + Deleting is hairy. There are mainly two nodes involved: the node to be + deleted (n1), and another node that is to be unchained from the tree (n2). + If n1 has a successor (the node with a smallest key that is larger than + n1), then the successor becomes n2 and its contents are copied into n1, + otherwise n1 becomes n2. + Unchaining a node may violate rule 1: if n2 is black, one subtree is + missing one black edge afterwards. The algorithm must try to move this + error upwards towards the root, so that the subtree that does not have + enough black edges becomes the whole tree. Once that happens, the error + has disappeared. It may not be necessary to go all the way up, since it + is possible that rotations and recoloring can fix the error before that. + + Although the deletion algorithm must walk upwards through the tree, we + do not store parent pointers in the nodes. Instead, delete allocates a + small array of parent pointers and fills it while descending the tree. + Since we know that the length of a path is O(log n), where n is the number + of nodes, this is likely to use less memory. */ + +/* Tree rotations look like this: + A C + / \ / \ + B C A G + / \ / \ --> / \ + D E F G B F + / \ + D E + + In this case, A has been rotated left.
