How to find an effective solution to the problem of changing the values ​​of variables according to the scheme (pictured)?

Question

C++ / C#

Hello! Here is such a task: to find an effective solution to the problem of replacing the values ​​of variables according to the scheme (pictured).

That is, it is necessary that these values ​​\u200b\u200bmove clockwise.
I decided to try to implement it like this (photo 2):

With the help of 3 picture boxes. That is, these 3 pictures should change with the help of a given algorithm. But how? I searched, looked, it seems that there is nothing like it anywhere, I decided to ask you. I may be making things more difficult by using picture boxes, but if you have any other ideas, please let me know.
Hope for help.

The simplest is a singly-directed list where the last element refers to the first. To calculate the current sequence - specify the initial element and go up to the list until it is found again.
