Tree Node

Description: A tree node is an individual element that is part of a data structure known as a tree. In graph theory, a tree is a type of graph characterized by being connected and acyclic, meaning it contains no cycles and there is a unique path between any pair of nodes. Each node in a tree can hold a value or information, as well as references to other nodes, known as its children. Nodes are organized hierarchically, where a node can be the parent of one or more child nodes, and in turn, can have a parent node. This structure allows for efficient representation of hierarchical relationships. Tree nodes are fundamental in various applications of computer science, such as in data structure representation, file organization in storage systems, and in search and sorting algorithms. The root of the tree is the top node, from which all other nodes branch out, and nodes that have no children are known as leaves. The depth of a node refers to the length of the path from the root to that node, while the height of a tree is the length of the longest path from the root to a leaf. This organization allows for efficient operations such as insertions, deletions, and searches, making tree nodes essential in graph theory and programming in general.
