There is an issue in this kata the test cases run smoothly but when I click attempt it says should work for n = 0 or something above those lines. I tried using and if statment then it says +0 should equal 1 when I change it to return 1 it says 1 should equal 0. I don't know how to debug this. this is the only test cases that isn't working.

For anyone wondering, this is definitely and absolutely NOT best practice! Its not even a clever solution.

5 years old issue is still not resolved. Bad kata

python new test framework is required. updated in this fork

Your code will compare numbers against itself (which fails for cases when n = 0) since the diff between a number and itself is always 0

Your solution does not take into account cases like arr = [8, 4, 0], n = 4. The expected result should be 2, but your solution returns 0

Use single quotes unless string interpolation is required.

• is one considered best practice over the other?
• why or why not?

the spread operator didnt always exist.

I think I did this efore the spread operator existed. So ...args wasn't valid.
