The sequential order of the interactions in an ATM system is following specific steps and in a strict order to withdraw money and as follow. The ATM machine will verify the client PIN card once he/she inserts his/her card into the machine. In case if the entered PIN is invalid, the Control Unit informs the client of that and the ATM machine asks the clients to re- enter the PIN number (after unsuccessful three attempts, the ATM machine eject the card and the control unit block the card). Once the entered number is correct, the ATM request the amount to withdraw in which the user provide this amount. The control then checks with the bank Database if the requested amount is sufficient enough. The database informs the ATM machine if the client's account carries sufficient amount to complete the transaction, after which, the ATM informs the client's if the transaction concluded or not. Draw the sequence diagram for the interactions described above. Show all method invocations and return values
