I found the puzzle below on the web. I would like to see my senior
students (who are learning very basic Prolog), turn this into a program
to find the answer.

currently there knowledge (and mine!), covers the basics, it does not
cover lists, though I would be willing to teach basic lists if it meant
they could work on this problem.

Could anyone advise what level of Prolog programming would be needed.

Thanks,
Cassandra Thompson
