## Challenge #148: Rotating Century Puzzle

:-) this is a good challenge - makes you think about base 6 numbering systems...

Super impressed with @jdunkerley79 's and @EstherB47  's solution (few tools - exhaust the problem space)

The approach here was to think about all the combinations for 1 slice first
- In other words - take the numbers which are at the 12 O'clock position in each ring, and call them slice 0; then go round the circle in clockwise order then you'll find slice 1, 2,3,4,5
- For slice zero - you create every combination of the inner 5 rings
- Once you know slice zero - you can derive the other slices fairly easily

The trick is to figure out the combinations by generating numbers; converting using base 6 math a set of 6 digits (each from 0 to 5).    This makes it much easier than generating 1 rotation for every ring.

Once you have this, you can then do a quick lookup to find the value written on the ring, and do a simple sum.

Looking forward to reading the solutions from other folk.

Here's my solution... an assisted one as I couldn't have done it without peeking at @jdunkerley79 's MOD function.
