damn you're right I didn't see that, my bad

thanks for observation, fixed the translation in the following fork

You have to convert them from one base to the other before applying the operator and back after that.

You should make the argument optional in your code I think. It's like that in other languages too.

Error in Java tests:

./src/test/java/SolutionTest.java:35: error: method orArrays in class OrArrays cannot be applied to given types;

       OrArrays.orArrays(new int[]{1, 0, 3}, new int[]{1, 2, 3}, 3));
                ^

required: int[],int[]
found: int[],int[],int

On researching bitwise operators it seems they apply to binary digits not decimal digits. I understand the output of OR is 1 if either of the inputs are 1 and 0 if both of the inputs are 0. How does this apply to decimal digits?
