Hi. I'm looking at a problem and I can't find any solution short of
coding.

I have a pool of, say, 1000 PINS. I have 7 tables (buckets). Any of
the 1000 PINS can be in 0, 1, 2, or... or all 7 buckets. So let's say
that

-bucket A has 100 PINS
-bucket B has 300 PINS
-bucket C has 600 PINS
-bucket D has 200 PINS
-bucket E has 500 PINS
-bucket F has 350 PINS
-bucket G has 700 PINS

I need to know, for each PIN, the number of buckets (tables) it
belongs to, and which ones, i.e:
- PIN 1 belongs to A, C, D, so it belongs to 3 buckets
- PIN 2 belongs to A, C, D, F, so it belongs to 4 buckets
- PIN 3 belongs to A, so it belongs to 1 bucket
- PIN 4 belongs to A, B, C, D, G, so it belongs to 5 buckets
- PIN 5 belongs to ..., so it belongs to 0 buckets
etc, etc

What would be the simplest way to achieve that, please ?

Thank you very much
Alex.
