Just out of curiosity, I see a lot of solutions where the individual nodes are stored in an array, returning the kth last entry of that array. Is this a generally acceptable way of doing this? Seems not to be in the 'spirit' of dealing with linked lists.
errrr... since when the element at "index 0" of a linked list is the last element of it...? :o
Aren't there any convention about this? I always remember the head as being equivalent to index 0 (cannot find quickly something meaningful on google, right now)
What does this have to do with the task?
@FArekkusu he's not asking of what the specs is, he's asking why the specs is that way.

This Kata, and the others in the linked list series, should be of a higher level, the point of these kata is very obscured, how to solve takes a bit deeper of knowledge then a lower level kata should require. At least, all of these should be in one of the yellow kata categories
Yes, it should be a 6 in my opinion too, but this is the average rating given by the beta solvers. This is basic CS stuff, so I guess people with CS background will rate it as easy.
PHP Translation Kumited - please accept :D
