Using semaphores, design a solution to manage clients access to five banking tellers given the following operation scenario: The bank has a space with 15 chairs and a standing area that can accommodate up to 10 clients. Hence, the maximum number of clients allowed to enter the bank branch is 25. A client needs to wait for an empty chair before sitting. A client will not be served except after receiving a ticket. To obtain a ticket, the client needs to enter his ID. When a teller is available, one.
