What are the applications of trees?

What are the applications of trees? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

The application of tree includes heap and its operation, Huffman tree, set and its operation; tree is an important nonlinear data structure. Intuitively, it is a data element, called node in the tree, organized by branch relationship, much like a tree in nature.

Related brief introduction:

Tree is an important nonlinear data structure. Intuitively, it is a structure in which data elements (called nodes in the tree) are organized by branching relations, much like trees in nature.

Define

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

(1) each element is called a node.

(2) there is a specific node called the root node or root (root)

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