The red-black tree is a self-balancing two-fork search tree, a data structure used in computer science, typically for associative arrays (Map/set in C + + STL). It was invented in 1972 by Rudolf Bayer, which he called "symmetric binary B-tree", and its modern name was obtained by Leo J. Guibas and Robert Sedgewick in a paper written in 1978. The red-black tree is complex, but its operation has a good worst-

A few months ago I was talking about black box testing is not necessarily less than white-box testing technology, but now I can be more positive that black box testing than white box testing more difficult, more technical requirements.

About the balance of the red and black trees-Conditions for deleting nodes [reprinted] There have never been any good articles or implementations about algorithm deletion on the Internet. I will write them down here to facilitate future use. The delete operation is always performed on a node with only one child or a leaf node, and will never be performed on a node with two children. The successor function is called only when there are two children in

Red and black TreesA red-black tree is a binary lookup tree, but adds a storage node color to each node, which can be red or black. By limiting the color of the nodes on any path from root to leaf, the red-black tree ensures that no path is twice times longer than the other paths, and thus is nearly balanced.Each node

I. Red/black tree Overview Similar to the AVL tree we have learned before, the red and black trees maintain a balance between the binary search trees through specific operations during insertion and deletion operations to achieve high search performance. However, since the emergence of the red and black trees, the AVL tree has been put in the museum. It is said t

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

Generation Principle of network Black HoleFriends who have some knowledge about network technology have encountered this kind of thing: without the support of UPS uninterruptible power supply, due to the sudden interruption of power supply, as a result, all devices in the company's data center, including routers, are stopped.

In this case, the small series know only two solutions, method one: Reinstall system or System Restore, only recommend the installation system and a very small number of software users, because the reload system has to reinstall the software. Method Two: Add the Administrator account, delete the original administrator account, desktop shortcuts are mostly lost, for the application reconfiguration desktop shortcuts. Here small series mainly for everyone to talk about method two bar. 1, first of
