The binary tree algorithm is an algorithm that will be learned when learning data structures in small editors. This can improve the search performance by 50% in search and sorting, let's take a look at some php binary tree traversal algorithms and
Binary tree traversal, is the value from the root node, in some order to access all nodes in the binary tree, so that each node is accessed once and only accessed according to
The picture is Baidu searches ... Thank you for the hero of the map.

1. recursion refers to explicitly calling itself in a function. Recursive tree structure is characterized by fast data writing speed and slow display speed (especially when there are many branches and layers of the tree ). Applicable to scenarios
Two methods for implementing tree structure
Recursion refers to explicitly calling itself in a function.
