[Data Structure] Nonlinear Structure – Tree (Basic Concept)
The standard definition of a tree: a finite set containing n (n>0) nodes.
1. Each element in the set is called a node (Node)
2. There is a special node called Root
3. The node ele

[Data Structure] Recursive and non-recursion realization of binary search trees
1. What is a binary search tree
1. Each node has a key code (key) as the basis for searching, and the key codes of all nodes are different from each other.
2. The key code (key) of all

[Data Structure] Red Black Tree
The red-black tree is a binary search tree. It adds a storage bit to each node to indicate the color of the node, which can be red or It can be black. By constraining the color of any simple path f
