You should know, apple is an 2D array. So, if you modified the second line j <= apple[0].length, and then your code will work correct ;-)

I can't test it, because CW's server doesn't work now.

EDIT: ++i and ++j may be i++ and j++, and <= may be <

EDIT: If you use ++i and <=, when i==apple.length, apple[i] == undefined, and then apple[i][j] will got an error.

Can you paste you code here? and mark it as having spoiler content.

sorry, I wasn't on when the issue was raised if it's still a problem please let me know :)

I deployed the fix! Please let me know if everything's fine now.

Sorry for the Inconveniences Caused.

Guys I'm sorry the person who created those Reinforcement Test Cases is not responding :/

I'll try to add a new version of Reinforcement Test Cases but I don't think that's possible because that kata is already approved and many users have solved it.

I'm facing the same problem too. Just update this thread once you're done fixing the test case.

I'm sorry but my knowledge about the test cases is a little bit rusty.

So, I'll notify someone to take a look into it.

I'm having the same issue.

I passed NaN as a string as suggested too.
