Description

Testing

This is a good catch to fixing this method. I have one question though which is why would the length of the has_part list not be sufficient enough to catch all the items. Are there cases like in the test record above where the length misses one of the items in the has_part array?

@mitri-slory great question. There are cases where the indices of the has_part array do not align with the number of parts. So for instance, there may be two parts but the indices are 2 and 3. In this case we would only be extending the array by 2 but we get an IndexOutOfBounds exception because of the has_part indices are greater than what we extended the array by.
