OP solved it, closing

Of course you can.

Closing this issue.

You should consider it.

No problem!

Look at your code above, CW had eaten the +?-)

Before posting an issue to the kata be sure your code is good!
Unfortunately your code is wrong in Python (and - I suppose - in JS too).
Sorry for that :-( but the kata is for nothing in your timing-out.

There are no undefined in the arrays. Codewars has lots of problems now. Try later...
I answer late but I have just been notified.

Yep, usually a kata gets a bunch of fixed and then many more random tests.

They are called "random test cases" for a reason and nothing prevents you from printing/logging inputs and the like :)

You should find 1 correct answers from all the math combinations. You can use the code to generate these combinations, rather than the way to use the typing.

I fixed it lolz

@yashaRO, this isn't an issue with the kata so I recommend you resolve it. I can help you with your code though, first things first. length is not a property of a number start with that, hopfully it helps :)

@Nav31, Create a new post above and paste your code and mask it as a spoiler and I can help you :)

Samething is happening to me also...

post your solution below and mark it as a spoiler and someone can help you :)
