This is the Way.

Can you explain precisely how this is a valid issue?

timed out with python code

I have no idea how to improve brute-force algorithm except some evident heuristics. However, they do not let avoid n! complexity

it worked, thanks :)

Fixed.

Language: Swift
Starting with the base code that uses Long type that does not exist in swift, after changing all variables to Int the base test works but when i try the big attempt it gives out this error:

main.swift:44:24: error: type of expression is ambiguous without more context

let actual = numbersWithDigitInside(x,d);

i think it's a test issue but if there is already a fix i'd like some help

I'm not sure there is a clear way to suppose the product to be 0 if we have no numbers

I liked this kata when i finally figured out the algorithm. It would be faster if there had more sophisticated examples, hinting the logic of such search.

It is nice to do like that

Nice approach!

It would be more deft to create a script to generate STRONGS
