Tree is an important non-linear data structure. Intuitively, it is the organization of data elements (called nodes in the tree) according to branch relationships. The structure is very much like a tree in nature.

Definition

A tree (tree) is a finite set composed of n (n>0) elements, where:

(1) Each element is called Node;

(2) There is a specific node, called the root node or root;

(3) Except for the root node, the remaining nodes It is divided into m (m>=0) disjoint finite sets, and each subset is a tree (called a subtree of the original tree).
