Could you try pasting your code again using ``` before and after your code in a separate line? See the link I posted above. Otherwise it lose indentation and some other things.I've copied/pasted your code but it gave me an error because something was lost without formatting.

You're welcome.

The brackets show the difference, the expected value has 2000 and your returned value hasn't that.
Mark your post as having spoiler content when pasting code like that and to increase the readability of comments or descriptions, see this page in the github wiki.
