c) We all know the producer-consumer problem. Explain in general terms, how a solution to the producer-consumer problem can help to serve the guests in a wedding ceremony problem. The food is brought to all the tables then the first batch of guests eat. After the guests complete eating, the tables are again filled with food so that the next batch of guests can start. Don't forget to mention who is the producer, who is the consumer, and what is the buffer in this scenario. Do you need any change in the producer-consumer solution to support this scenario? If yes then explain the change. d) Name the three conditions any solution for the critical section must meet. Give an example of a problem that can happen if any condition is violated for all three conditions. [3]
