Data Structure

Tree, Forest, and Binary Tree Transformation refer to some common data structure concepts in computer science. A tree is an abstract data type that consists of nodes and edges connecting these nodes. A characteristic of trees is that each node has at most one parent node, but can have multiple child nodes. Usually, a tree structure has a special node called the root node, which is located at the top of the tree and has no parent node. Tree structures are widely used in computer science, such as file systems, database indexes, organizational structures, etc.
