It passes non-integral numbers as inputs, it doesn't implement the specs ( x+y<=27 ), the description is still bad, the examples aren't language-specific, the initial code has a spelling error in the funtcion name, said function name doesn't adhere to camelCase standard, the example tests are too limited to catch solutions that switch x and y, the output datatype should be a 2D array of strings instead of a string.

All in all, not too good. Neither the kata itself nor the translation. Consider focusing on solving two month old issues instead of creating new translations.

for int arrays you need to return ints. but you are returning array of chars.

Not an issue, you should return an array of numbers when the input was also an array of numbers.
