Introduction The red/black tree is a self-balancing Binary Search Tree. Its statistical performance is better than that of the balanced binary tree (AVL Tree). Therefore, the red and

In practice, we do not directly use the Binary Search Tree, because the performance of the Binary Search Tree is heavily dependent on the insertion sequence of elements, especially when an element is inserted in an ascending manner, in this case, the binary search tree will become a linked list. In practical applications, we use the "balanced" binary search tree, including the AVL, red, black, and AA trees, the most commonly used is the red/

1. Introduction The red-black tree is a self balanced binary lookup tree. Its statistical performance is better than the balanced binary tree (AVL tree), so the red-black tree is used in many places. In C + + STL, many parts (currently including set, Multiset, map, Multimap) apply the variant of the red-black tree (there are some changes in the red-

First, the problem descriptionImplement two of the 3 types of trees: red-black, AVL, treapSecond, the principle of the algorithm(1) Red and black treesA red-black tree is a binary lookup tree, but adds a storage bit to each node that represents the color of the node, which can be red or black. The red and

Red/black tree, Http://blog.csdn.net/sun_tttt/article/details/65445754 The red-black tree is a balanced binary tree, but it is not a perfect balanced binary tree.Although we hope that all searches can be found in ~ The lgN comparison ends, but it is too costly to maintain a perfect balance between the trees during dynamic insertion. Therefore, let's just relax and look at the limitations, we hope to find a

I. OverviewRed-black tree is a classic storage structure, in itself is a binary search tree, just on this basis, the tree node added a property to represent the color (red or black). By restricting the coloring of nodes from the root node to the individual paths of the leaves, it is ensured that no path will exceed twice times the length of the other path, so that the red-

Finally, we will explore the red and black tree deletion algorithm, compared to the insertion operation, it is more complex situation. So it's easy to get into the south wall, we need to use the idea of conversion and transformation (remember the four ways of thinking in high school math, as applicable here), by raising the change, the red black tree mapped into a b- tree, and stand in the latter angle, in

It's still the same, first of all: Property 1. nodes are red or black Nature 2. The root is black Nature 3. All leaves are black (leaves are nil nodes) Nature 4. If a node is red, its two sons are black 5. All simple paths from any node to its leaves contain the same number of bla
