It appear the developers on Chegg are unable to answer most question. Questions are closed without answers nor communication of why it was closed. I received one answered question which was incorrect and the code provided by Chegg did not work. it appear this site string you along to collect money knowing they are unable to solve most questions. Most important they do not communicate why they could not answer the question. Chegg closes its customer questions without communication. Thus treating their paying customers as unimportant individuals.
