A tree data structure is a hierarchical data structure that consists of a collection of nodes connected by edges. Each node in the tree represents an element, and the edges represent the relationships between these elements. The topmost node in the tree is called the root, and the nodes below the root are called child nodes. The nodes without any child nodes are called leaf nodes.
Key Characteristics of Trees:
Hierarchical Structure: Trees have a hierarchical structure, where each node (except the root) has a single parent node, and each node can have multiple child nodes.
Non-linear Data Organization: Unlike linear data structures like arrays and linked lists, trees organize data in a non-linear fashion, allowing for more efficient storage and retrieval of information.
Recursive Definition: Trees can be defined recursively, where a t...
