Tree structure - Wikipedia
A tree structure, tree diagram, or tree model is a way of representing the hierarchical nature of a structure in a graphical form. It is named a "tree structure" because the classic representation resembles a tree, although the chart is generally upside down compared to a biological tree, with the "stem" at the top and the "leaves" at the bottom.
Introduction to Tree Data Structure - GeeksforGeeks
2025年1月2日 · Tree data structures are hierarchical models that represent data through parent-child relationships, featuring key concepts such as root, leaf, internal nodes, and various types like binary and n-ary trees, making them essential for organizing information in a non-linear format.
Tree (abstract data type) - Wikipedia
In computer science, a tree is a widely used abstract data type that represents a hierarchical tree structure with a set of connected nodes.

2025年1月2日 · Tree Data Structure is a non-linear structure consisting of nodes connected by edges, with various types and applications, including Binary Trees, AVL Trees, and B-Trees, each having specific properties, traversal methods, and operations like insertion and deletion.
Tree Data Structure - Online Tutorials Library
A tree is a non-linear abstract data type with a hierarchy-based structure. It consists of nodes (where the data is stored) that are connected via links. The tree data structure stems from a single node called a root node and has subtrees connected to the root.

2025年1月15日 · What is a Tree Data Structure? A tree in data structures is a collection of objects or entities known as nodes that are connected by edges and have a hierarchical relationship between the nodes. The topmost node of the tree is called the root node from which the tree originates, and the nodes below it are called the child nodes. Each node can ...
Tree Data Structure: Types, Examples, Operations, Full Guide
What is Tree Data Structure? A tree in DSA (Data Structures and Algorithms) is a way to organize data. It looks like an upside-down tree with a root at the top and branches spreading out. Each point on the tree is called a node, and the lines connecting them are called edges. The top node is the root, and nodes with no children are called leaves.
