Red-black tree is a very good performance data structure, the key is that it can ensure that the worst performance is also logarithmic, mainly because it is a balanced tree, so also called the balance of the search tree. To understand the red and black trees, it's best to take a look at my previous blog, "Algorithm 4" symbol table and the two-fork lookup tree, to understand the binary lookup tree and why we

OverviewAbout the basic knowledge of red and black trees in the previous article has been introduced, want to learn more about red and black tree can refer to the article "Data structure-red black tree", here is only simple to nginx in the red and black tree source of the analysis, Nginx red and

Http://www.cnblogs.com/yangecnu/p/3627386.htmlThe previous article introduced the 2-3 lookup tree, you can see that the 2-3 find tree can ensure that after inserting elements can maintain the balance of the tree, the worst case is all the child nodes are 2-node, the height of the tree is LGN, thus guaranteeing the worst case of time complexity. However, 2-3 trees are more complex to implement, this paper introduces a simple implementation of 2-3 tree data structure, that is, red-

subtree of the parent node of P.(3) If the left and right subtrees of the deleted node p are not empty, there are two ways: Set PL to the left or right child node of P's parent node Q (depending on p is the left and right child node of its parent node Q), set PR to the right child node of the middle order forward node s of the P node (s is the most right node of PL, which is the largest node in the PL subtree). In order to replace the point of P node with the pre-order or successor

Delete operations are more complex than inserts. First, let's look at some of the characteristics of red and black trees. These are my random list, for everyone's reference.1, the red node Father black child must be black. (Nil is a black node)2, single branch node, can only be bla
