**a nonlinear data structure**, compared to arrays, linked lists, stacks and queues which are linear data structures. A tree can be empty with no nodes or a tree is a structure consisting of one node called the root and zero or one or more subtrees.

## What is tree in algorithm?

A tree is **a hierarchical data structure defined as a collection of nodes**. Nodes represent value and nodes are connected by edges. A tree has the following properties: The tree has one node called root. The tree originates from this, and hence it does not have any parent.

## What is tree in data structure?

A tree is **non-linear and a hierarchical data structure consisting of a collection of nodes such that each node of the tree stores a value and a list of references to other nodes** (the “children”). This data structure is a specialized method to organize and store data in the computer to be used more effectively.

## What is a tree in a graph?

In graph theory, a tree is **an undirected graph in which any two vertices are connected by exactly one path**, or equivalently a connected acyclic undirected graph.
