Criterion about passing the common road exercise

I have successfully solved over 340 scenarios, but I used some codes from the provided algorithm, which is not exectly same. From previous answer of the posted question, we are allowed to copy parts of codes. But is there criterion about passing the exercise? like what percent of my code should be original? if there is only slightly different about implementing method, is it acceptable for passing? Thanks!

Hi a11,

Thank you for your question.

I think there is no certain rule about how much you can copy the code we provide. As long as your algorithm works, it is acceptable even if it is only slightly changed.

Best,
