Each node of the red/black tree has one attribute.Key,3Pointers:Parent,Left,RightIn addition, there is an additional attribute:Color. It can only be in two colors: red or black,Of course, you can also add someKeyTo index the data. In addition to all the properties of the Binary Search Tree, the red/black tree also has the following5Point nature:

Recently want to write some about the red and Black tree blog, both want to write a comprehensive, but also intuitive, but do not know where to start. Start writing from the simplest two-fork sort tree.Binary sorting tree (binary sort trees) is also called Binary search tree. It is a special structure of a two-fork tree. It is either an empty tree, or has the following properties:(1) If its left subtree is
