Finger search algorithm?

Question

Algorithms

It is necessary to implement the Finger search algorithm (finger search?). As I understand it, you will have to implement a data structure (different types of trees). Somehow I didn’t really manage to find theoretical material in order to start implementing it.
You may have links to resources.

Answer 1

How could they not find it? Where were you looking for?
Well, here are the first links from Google:
https://en.wikipedia.org/wiki/Finger_search
https://www.leda-tutorial.org/en/unofficial/ch03s0...
https://www.freecodecamp. org/news/search-algorithm... - here even with example codes.
What's wrong?
