Programming homework 1) Simulated waiting queue in an Indian post office: In an Indian post office that not only distributes mail but also performs some financial activities like a savings bank, a lone postal worker attends to a single lineup of clients. As soon as a consumer enters the line, they are given a token # (serial number). After receiving assistance, the consumer exits the queue while the postal worker receives the token back. The employee could inquire as to how many consumers are still unattended at any one time. i) Put the system into practise using a suitable queue data structure, simulating the arrival and departure of consumers at random when the service is finished.

Bus Loading Problem. You are in charge of filling busses with passengers at a bus terminal. Each bus has space for ten (10) passengers. Four (4) of those spaces can hold only wheelchair passengers, and the other six (6) can hold only non-wheelchair passengers.  Busses and both types of passengers arrive at random. As busses arrive, you are to fill them up with passengers. Once a bus is full (containing 6 non-wheelchair, and 4 wheelchair passengers), it is allowed to leave the terminal, along with its passengers.

Each passenger process has available to it the functions ArriveAtTerminal() and GetOnBus(). Executing GetOnBus() loads the passenger on the bus, and the function returns when the…

Programming assignments1) Waiting line simulation in an Indian post office:In an Indian post office that not only delivers mail but also functions as a savingsbank carrying out specific transactions, a lone postal worker serves a single queue ofcustomers. Every customer receives a token # (serial number) as soon as they enterthe queue. After service, the token is returned to the postal worker, and the customerleaves the queue. At any point in time, the worker may want to know how manycustomers are yet to be served.i) Implement the system using an appropriate queue data structure, simulating arandom arrival and departure of customers after service completion.ii) If a customer arrives to operate their savings account at the post office, thenthey are attended to first by permitting them to join a special queue. In such a case,the postal worker attends to them immediately before resuming their normal serviceof mail delivery. Modify the system to implement this addition in service
