Read the case-study below and determine the data structure(s) that could be used to solve the problems identified in the case- study. Give a single sentence for each problem and explain why you have chosen the particular data structure for that problem. In a gas station system, three types of components are involved, which are customer, cashier, and pump. A customer always makes payment to a cashier before requesting gas from pump. The payment requests are buffered in cashier's buffer and the cashier processes the payment requests in order. Whenever the cashier receives a payment from a customer and record the payment successfully, the cashier asks the pump to release gas for that customer. Note however that pump may respond to the cashier that no gas is available and the cashier then cancels the last payment made from the list of recorded payments. Also, the pump may buffer any requests made by the customers and the first received request is served first assuming that the gas is available and the cashier already requested to release gas for that customer.

Question
Transcribed Image Text:Read the case-study below and determine
the data structure(s) that could be used to
solve the problems identified in the case-
study. Give a single sentence for each
problem and explain why you have chosen
the particular data structure for that
problem.
In a gas station system, three types of components are involved, which are customer, cashier,
and pump. A customer always makes payment to a cashier before requesting gas from pump.
The payment requests are buffered in cashier's buffer and the cashier processes the payment
requests in order. Whenever the cashier receives a payment from a customer and record the
payment successfully, the cashier asks the pump to release gas for that customer. Note
however that pump may respond to the cashier that no gas is available and the cashier then
cancels the last payment made from the list of recorded payments. Also, the pump may buffer
any requests made by the customers and the first received request is served first assuming
that the gas is available and the cashier already requested to release gas for that customer.
