Not my own modeling
which problem?
Well I guess my question is which type will have the least problems
So you don't know, for instance, if 2 am even exists.
Cargo handlers at airports have a limited number of truck docks, and they have time slots based on wall time during which those docks are available. They want freight forwarders to make an appointment for those slots. They don't care which truck dock they take, as long as the dock has the right facilities. A system to manage dock availability and reservations sounds a bit like your problem. If it is, I do think I have some idea about such a system.
i think '@ the type level' is rather vague, https://www.youtube.com/watch?v=gVXt1RG_yN0 but this talk was enlightening for me
Im trying to take a list of lists of characters and converting it into a list of characters inserting a '\n' character between each two lists
the part i get hung up on is the
inbetween lists part
You can use the
prepend operator :+ to add to the end of a list (List(1, 2, 3) :+ 4) == List(1, 2, 3, 4), and combine it with a fold a la List(List('f', 'o', 'o'),List('b', 'a', 'r'),List('q', 'u', 'x')).foldLeft(Nil:List[Char])((acc, cs) => acc ::: (cs :+ '\n’))
>List(f, o, o,
, b, a, r,
, q, u, x,
)
The only problem will be that the last element will have a newline after. To fix that, you’ll have to use fold in conjunction with a pattern match
I’ll leave that up to you
i would pattern that the next item isnt Nil correct?
not that there's anything wrong with that
It's interesting that
takeRightWhile is missing too. I must have a nosy at these new collections
i would guess i would that i would patten match on elem but how would i know its the last item?
case x::Nil?
