All of the submissions for “accumulate” are failing tests, or the tests are failing to run. It’s a fairly simple exercise and all of the solutions are the same / similar.
What is your code?
What does “failing” mean? Is there any output? What is it?
I’ll include my code since you asked, but you can see that all of the community solutions are failing as well, so my code is likely not the problem (also works locally with guile or chez scheme):
(define (accumulate f xs)
(if (null? xs)
'()
(cons (f (car xs)) (accumulate f (cdr xs)))))
By failing, I mean under “tests” it says:
AN ERROR OCCURRED
An error occurred while running your tests. This might mean that there was an issue in our infrastructure, or it might mean that you have something in your code that’s causing our systems to break.
Please check your code, and if nothing seems to be wrong, try running the tests again.
take a look at the community solutions and see that they all have a red dot (failing tests):
It seems that the problem has been reported a while ago. But I myself have observed the same problem. I even tried
(define accumulate map)
which cannot fail. What is puzzling me is why this particular problem fails while all other problems did not. Does anyone have any idea?
