yes? I'm not an authority. but I recal in class he used two different techniques (exhaustive enumeration vs bisection search) which each yielded different answers. but he said they were both valid. regarding your negative answer, I thought the problem set said that was okay too. 

again. I'm not an authority. nor can I see your code. nor would I be able to give you an answer even if I could see you code.
