I. Characteristics of red and black trees1. The node can only be red or black.2. The root node is black.3. Leaf node (NIL) is black.4. The child node of the red node must be a black node.5. The path to the descendant nodes of any node that reaches the node contains the same

1. Red and black tree (Red-black trees) Introduction:The Red-black tree (RBT) can be said to be a non-strict balanced version of the Binary-search tree. Correspondingly, the Balanced binary tree (Balanced binary trees) is also called the AVL tree (because it is g.m. The tree Adelson-velsky and E.M Landis invented in 1962 is a strictly balanced version of Binary-s

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-

Deleting a node can also change the balance of the tree, and the imbalance caused by the deletion is more complex than the balance correction caused by the insertion. Simplification is a common method in algorithm analysis. Below we will want to delete the node into three main categories: to delete the node as a leaf node, to delete a node only one child node and to delete has two child nodes. There are two possible colors for deleting nodes, and they need to be treated separately. To simp

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
