Thanks to the kata creator 🙌 — fun challenge on array iteration and difference calculation!

because it's readable and the intention is clear; no one can seem to figure out why .digits does what it does

Description should be language-agnostic

JS Node 18. should be enabled

Here's an iterative stack-based solution

Same for Python and presumably other languages, another occurrence:

[-7, -4, 4, 6, 3, 5, 1], -9

Not really an issue, no performance tag, no explicit mention of large arrays. A performant version may be created but I doubt if it is any different than myjinxin's three sum and four sum kata (potentially others ... ->

• simple fun ? a + b + c
• simple fun ? a + b + c + d

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

Approved

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
