Factorial function seems to not work

[yohannesm]

I can't refer the variable result that's definitely in scope for the function for some reason.

Also, Looking at the source code, the code is actually different than the one shown here.

Thanks for reporting this. Why are you trying to subtract result here? When expanding the function call for factorial(3) and factorial(4) on paper what will your solution yield?

[yohannesm]

oh my bad. It should be -1. Instead of result, but I still feel weird why I can't reference that whilst it's being referenced next to it. Anyway you can close it then, not really an issue.

[FRosner]

No problem. I agree with you that it is weird and I am curious about the difference in the code. Could you send a link to the line in the code? You can do so by opening the file on GitHub and then clicking on the line number. Then you can copy the link from your address bar :)

def factorial(n: Int): Int =
if (n == 1) n
else factorial(n - 1) * n

factorial(3) shouldBe 6
factorial(4) shouldBe 24

this is not working as is coming back with error ERROR -> not found: value n at [224, 224, 224]

I run the code in my IDE and is working buty in your test n is not recognised.

Error related to dependency was shown whatever I put in the answer box in this Function Loops tutorial page.
