Find all combinations of two arrays

I am trying to find all the combination of two arrays, but with an important variation:

Just for illustration, this is a version of @NinaScholz's answer that doesn't use toString for base conversion or implement counting manually. I've kept the structure of the code the same. values.length-i-1 could simply be `i', but I wanted to keep the order of the output the same too.

        m;
    for(m=0; m
