Binary trees are enormously used in data structure as they can be easily stored, manipulated, and retrieved. The most straightforward and extensive applications of binary trees are in the study of computer searching and sorting methods, binary identification problems, and variable binary codes. Many complex networks are easily classified and analyzed by the usage of binary tree representations. A binary tree is defined as a tree in which there is exactly one vertex of degree two and each of the remaining vertices is of degree one or three. Every binary tree is a rooted tree with odd number of vertices. A special type of binary tree known as hypertree is an interconnection topology which combines the easy expansibility of tree structures with the compactness of the hypercube. In this paper we find the Wiener index of hypertree. © Springer Nature Switzerland AG 2019.
