There is a dining hall of capacity of 10 people at the most in a restaurant where families come to enjoy delicious food. On weekends, however, there is a great crowd in the restaurant. A person would be entertained only if there is a vacant chair. If all the seats are full, it means that there is a single family of 10 members enjoying the dinner. In this case, the person has to wait until the family leaves. Write a synchronization solution using semaphores for the customers entering and leaving the dining hall.
