Path Mapper component operation understanding

Grasshopper

Hello guys, ive been trying to understand the Path mapper component, recently ive tried to do some basic lexical operations, and in my understanding the {A} is a set where i get to shift the indices of it by the syntax {A-1} in my particular grasshopper script attached below

Would like to know what exactly is been happening here, thank you!

Elefront plugin is required, apologies for this as i ve referenced rhino geometry that , but ive internalized that into a BREP for you guys to begin

please find the .gh script below

Hi Vasanth,

This may help you understand the Path Mapper better: Rhino Grasshopper - Chapter 3: Advanced Data Structures 3.6.3

It is part of the documentation Rhino - Essential Algorithms and Data Structures for Grasshopper which is full of good stuff.
