Consider the following representation of a queue ADT that is implemented using an array data structure: Queue front rear 3 8204 0 1 2 3 4 5 Write the required C++ computer program instructions for the following functions: a) printNext()- which displays the next element in the Queue to be processed b) enqueueAt(data, position) - which insert data at location position in the Queue c) dequeueFrom(position) - which removes the Queue's element from location position, and ensures that all elements in the queue are adjacent (i.e. there are no gaps between elements in the queue) d) howMany(data) - which searches the Queue for data, and then returns the amount of elements in front of data before it is processed 6

Question 1 ( C++ pseudo code) Design a queue using only stacks. It must support the enqueue and dequeue operations. If you start with an empty queue, end up enqueuing and dequeuing k elements, what is the total running time using your data structure? Full explain this question and text typing work only thanks
C++ program that asks the user for an integer n followed by n other integers,if integer is prime then it adds it to a queue otherwise add it to a stack,then print both structures

BankCustomerQueueADT Implement in C++ a BankCustomer QueueADT that does the following: 1. gets the input about a customer (first name, last name, Bank Account Number, Money to be withdrawn/deposited, etc.) from the user (from the keyboard) 2. inserts (enqueues) the Customer as a record into the BankCustomerQueueADT (your Queue ADT must be able to have a maximum of 20 customer records) 3. removes (dequeues) the Customer record from the BankCustomerQueueADT 4. your BankCustomerQueueADT must also have the behavior of retrieving and displaying the Queue info on the screen after each event (either entry of a Bank Customer into the queue, OR leaving of the Bank customer from the queue). NOTE: Please make sure you debug, run, test and see the program working correctly before submitting. Make sure all the code statements are commented. Make sure your program is indented properly.
1. A company wants to evaluate employee records in order to lay off some workers on the basis of service time (the most recently hired employees are laid off first). Only the employee ids are stored in stack. Write a program using stack and implement the following functions: Main program should ask the appropriate option from the user, until user selects an option for exiting the program. Enter_company (emp_id)- the accepted employee id(integer) is pushed into stack. Exit_company ()- The recently joined employee will be laid off from the company Show employee ()- display all the employees working in the company. count()- displays the number of employees working in the company. i) ii) iii) iv)
