binary tree

A binary tree is a data structure used in computer science, where each node has at most two children, referred to as the left and right child. This structure resembles an inverted tree, with a single top node called the root, from which branches extend downward. Binary trees are useful for organizing data hierarchically, enabling efficient searching, inserting, and deleting of items. They form the basis for more complex structures like binary search trees and heaps, which optimize various operations and improve performance in tasks such as database indexing and expression parsing.
