Wiener, in 1947, firstly introduced the concept of the topological index while working on a boiling point . In particular, Hosoya polynomial [ 7 ] plays an important role in the area of distance-based topological indices; we can find out Wiener index, hyper-Wiener index, and Tratch-stankevich-zefirove index by Hosoya polynomial [ 8 ].
