Challenge #148: Rotating Century Puzzle

"The wheel is turning and you can't slow down,
You can't let go and you can't hold on,
You can't go back and you can't stand still,
If the thunder don't get you then the lightning will."

Listening to Grateful Dead to help me thru this one.

Used a brute force approach but got the same answer...

I liked the idea of ratcheting the rings round 1 by 1, so I went with an iterative macro. Not the most performant solution, but in my head I can hear the 'tick' as it turns each ring round by one position.

Not the most dynamic solution I'm afraid, but it does work



The macro looked like this:



The formula tools all had the same formula in:

MOD(([Position]+floor([Engine.IterationNumber]/pow(6,[0-5])))-1,6)+1

where the power of 6 would change for each input from 0 to 5
