yield - Scala beginner for-comprehensions and functions -


hey guys new scala , dont knowe doing wrrong right typ yield statement:

def prim(n:int): (boolean, list[int]) = divsers(n) -> list(1,n) //flatmap for-comprehensions  def divsers(n:int):boolean=  (for{     d <- 1 n     if((n%d)->0)    }yield(d) // <- need put here make work function prim?   )  prim(11);

i want test if number prime number. realy have got realy problems syntac , typs.even if put "true" in yield dont work?

you're doing kinds of things make no sense.

divsers(n) -> list(1,n) point of returning tuple who's 2nd element list of 2 ints? 1st int 1 , 2nd int number passed argument prim().

if((n%d)->0) you've created tuple here. mean if (n%d) > 0.

yield ? for comprehension walking through sequence of numbers 1 n. of them pass through if condition , won't. you've got new list of numbers. how you're supposed turn boolean you.
