The previous blog mainly describes the basic concept of two-fork sorting tree and insert delete operation, it must be explained again: In a height of two-fork sorting tree, the implementation of dynamic collection operation query, insert and delete run time is O (h).The basic operational efficiency of the binary tree is determined by the shape of the tree, of course, the lower the height of the tree is better, obviously, the more evenly distributed tree, the lower the height. So, what's the prob

Original link: TreeSet and TreeMap References: Data structures-common tree red-black Trees: A red-black tree is an approximately balanced two-fork lookup tree that ensures that the height difference between the left and right subtrees of any one node does not exceed that of the lower of the two.

Easy to understand the operation principle of red and black trees.

This week I wrote a red/black tree. I have to say that the red/black tree is a complex and hard-to-write data structure. Even though I close my eyes and can restore how to insert data, I still cannot delete it if I have enough time to write no data. There are not many experiences in deleting parts. Because left-right a

2-3-4 trees and red/black trees may look completely different. However, in a sense, the two are exactly the same. There is a data item and two subnodes are called 2-nodes. There are two data items and three sub-nodes called 3-nodes. Three data items and four subnodes are called 4-nodes. Rules for converting from 2 to 4 trees to red/
