Finding this very difficult - not complaining, it's how it should be. Araucaria at his best I reckon.
Couple of questions:
Are all intermediate words "real" words as in example (ie cone, lone, line & lice) - realise first and last 4 letter words don't have to be (ie conf & lict)?
Are there always just 4 "steps" as in example? ie each starting letter changed just once.
Any hints gratefully accepted!
Thanks in advance.
