The next step is to introduce the red-black tree Insert, before inserting, let's first look at the nature of the red-black tree.1, each node is not red or black2, with the node is black.3, if the node is red, the child node must be black.4, any node to the end of the tree any path,

Before we learn binary search tree when hair now in some cases its height is not very uniform, and sometimes degenerate into a long chain, so we quoted some "balanced" two-fork search tree. The red and black tree is a "balanced" two-fork search tree, which ensures that in the worst case, the time complexity of the basic dynamic set operation is O (NLGN) by attaching the color bits and paths on each node. The following summarizes the nature of the red

The world's largest scientific instrument, the large Large Hadron ordinator, was officially launched in Switzerland on the 10th.

Scientists say this worry is superfluous, but if you really fall into the black hole, what will happ

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.

The red and

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
