Ok i see moust of the votes go for 6 kuy. I will change the expected rank to 6 kyu.

Thank you i fixed the non-integral inputs and the function is now in camelCase standart.

It has a section for the specific languages, but i just realized it's not working. It is just showing them all.
I changed the names of the sections to java , python and javascript

And it is now working for Java and Python, but when JavaScript is selected it shows Java too.
How can I fix that ?

I will probably remove that restriction (x+y<=27) and say that the matrix builds only with the alphabet chars.
Because it's more like a note to tell people there is no need to check just start from 'a' and go on to 'z'. Just like you did in your solution.

JavaScript translation added. Any feedback is welcome.

Approved. Thank you for the translation.

You are right. Im fixing that.

Formatting added.
Hope it looks better now.

Thank you for your advices.

I get this error with int arrays Expected: '[1, 2, 3]', instead got: '['1', '2', '3']'
and my code passed char arrays Test Passed: Value == '['a', 'b']'
the expected output of int arrays seems wrong !
