Basic Concepts
The level of a node is defined from the root. The root layer is the first layer, and the child of the root layer is the second layer.
The height of a binary tree: the maximum level of a node in the tree is called the depth or height of the tree.Binary Tree
In computer science, a

Title one: Print binary tree from top down
Each node of the two-fork tree is printed from top to bottom, and the same-level node prints from left to right.
The topic Analysis: This problem actually examines the tree traversal algorithm, the traversal usually has the preface, the middle order, the post-order traversal,

Basic ConceptsThe level of the node is defined from the root and the root is the first layer and the child of the root is the second layer.Height of the binary tree: the maximum level of the node in the tree is called the depth (Depth) or height of the tree.Two fork TreeIn computer science, a binary

definition
Binary tree is a finite set of n (n>=0) nodes, which is an empty set called an empty binary tree, or has a root node and two separate left child trees and right child trees, called root nodes, which are disjoint.
two characteristics of the fork tree

B-Tree is a binary search tree:1. All non-leaf nodes have a maximum of two sons (left and right);2. All nodes store a keyword;3. The left pointer of a non-leaf node points to a subtree smaller than its key, and the right pointer points to a subtree larger than its key;Such as:B-Tree search, starting from the root node,
