You are developing an order processing system for a company. To efficiently manage incoming orders, you decide to implement a queue data structure using an array. The queue will store order IDs. Implement the following operations:Insert Order: Add an order ID to the end of the queue.Process Order: Remove and process the next order ID from the queue.Display Queue: Display the order IDs in the queue.Input format :The input consists of an integer option representing the action to be performed:Option 1: Enqueue a new order ID into the queue. The next line contains an integer representing the element to be inserted.Option 2: Dequeue an order ID from the queue for processing.Option 3: Display the list of order IDs currently in the queue.Output format :The program provides appropriate outputs based on the choice:When enqueuing an order (option 1), the program outputs the order ID that is inserted into the queue.When dequeuing an order (option 2), the program outputs the order ID that is being processed.When displaying the order IDs (option 3), the program shows the order IDs in the queue.If an enqueue operation is attempted when the queue is full, the program outputs "Queue is full."If a dequeue operation is attempted when the queue is empty, the program outputs "Queue is empty."If the user provides an invalid option, the program outputs an "Invalid option."Refer to the sample output for the exact text and format.Code constraints :The maximum size of the queue is defined as max = 5.The queue can store integer values.Each order is identified by a unique positive integer order ID.Sample test cases :Input 1 :1103Output 1 :Order ID 10 is inserted in the queue.Order IDs in the queue are: 10 Input 2 :13014023Output 2 :Order ID 30 is inserted in the queue.Order ID 40 is inserted in the queue.Processed Order ID: 30Order IDs in the queue are: 40 Input 3 :34Output 3 :Queue is empty.Invalid option.Input 4 :110120130140150160Output 4 :Order ID 10 is inserted in the queue.Order ID 20 is inserted in the queue.Order ID 30 is inserted in the queue.Order ID 40 is inserted in the queue.Order ID 50 is inserted in the queue.Queue is full.

Solution
Sure, here is a Python implementation of the order processing system:
class OrderQueue:
def __init__(self, max_size):
self.queue = []
self.max_size = max_size
def enqueue(self, order_id):
if len(self.queue) < self.max_size:
self.queue.append(order_id)
print(f"Order ID {order_id} is inserted in the queue.")
else:
print("Queue is full.")
def dequeue(self):
if len(self.queue) > 0:
print(f"Processed Order ID: {self.queue.pop(0)}")
else:
print("Queue is empty.")
def display(self):
if len(self.queue) > 0:
print("Order IDs in the queue are: ", end="")
for order_id in self.queue:
print(order_id, end=" ")
print()
else:
print("Queue is empty.")
def process_orders():
order_queue = OrderQueue(5)
while True:
option = int(input())
if option == 1:
order_id = int(input())
order_queue.enqueue(order_id)
elif option == 2:
order_queue.dequeue()
elif option == 3:
order_queue.display()
else:
print("Invalid option.")
process_orders()
This script creates an OrderQueue class to manage the queue of orders. The enqueue method adds an order to the queue, the dequeue method removes an order from the queue, and the display method shows the current state of the queue. The process_orders function is the main loop of the program, which reads the user's input and performs the corresponding operation.

Priya is designing a supermarket checkout queue system to efficiently manage customer flow at the supermarket. Customers join the checkout queue, and cashiers process their orders. Her goal is to implement the core functionality of this system using a queue data structure with an array. Add Customer to Queue: Add a customer to the checkout queue. Each customer is identified by a unique customer ID.Delete Customer: Remove the customer at the front of the queue. Display Queue: Display the customer IDs of all customers in the queue.Help her in designing the program.Input format :The input consists of integers corresponding to the operation that needs to be performed:Choice 1: Add a customer to the queue. If the choice is 1, the following input consists of a space-separated integer, representing the customer ID.Choice 2: Dequeue a customer ID from the queue.Choice 3: Display the list of customer IDs waiting in the queue.Choice 4: Exit the program.Output format :The output displays messages according to the choice and the status of the queue:If the choice is 1:Insert the given customer ID into the queue and display "Customer ID [id] joined the checkout queue." where [id] is the customer ID that is inserted.If the queue is full, print "Checkout queue is full."If the choice is 2:Dequeue a customer ID from the queue and display "Processed Customer ID: " followed by the corresponding ID that is dequeued.If the queue is empty without any elements, print "Checkout queue is empty."If the choice is 3:The output prints "Customers waiting in the checkout queue: " followed by the space-separated customer IDs present in the queue.If there are no elements in the queue, print "Checkout queue is empty."If the choice is 4:Exit the program and print "Exiting Program"If any other choice is entered, print "Invalid option."Refer to the sample output for the exact text and format.Code constraints :Maximum size of the queue = 5Choice: 1, 2, 3 or 4.Sample test cases :Input 1 :1 101 1 102 234Output 1 :Customer ID 101 joined the checkout queue.Customer ID 102 joined the checkout queue.Processed Customer ID: 101Customers waiting in the checkout queue: 102 Exiting ProgramInput 2 :1 1301 140232324Output 2 :Customer ID 130 joined the checkout queue.Customer ID 140 joined the checkout queue.Processed Customer ID: 130Customers waiting in the checkout queue: 140 Processed Customer ID: 140Checkout queue is empty.Checkout queue is empty.Exiting ProgramInput 3 :384Output 3 :Checkout queue is empty.Invalid option.Exiting ProgramInput 4 :1 201 1 202 1 203 1 204 1 205 1 20622234Output 4 :Customer ID 201 joined the checkout queue.Customer ID 202 joined the checkout queue.Customer ID 203 joined the checkout queue.Customer ID 204 joined the checkout queue.Customer ID 205 joined the checkout queue.Checkout queue is full.Processed Customer ID: 201Processed Customer ID: 202Processed Customer ID: 203Customers waiting in the checkout queue: 204 205 Exiting Program
You are tasked with implementing a circular queue to manage a list of integers. Your circular queue should support the following operations:Insert an element: Add a new integer to the queue.Delete an element: Remove an integer from the front of the queue.Display the queue: Print all the elements in the queue in their current order.Note: The queue can hold up to MAX = 10 elements.Input format :The input consists of an integer choice which determines the operation to be performed:1: Insert an element into the queue, If the choice is 1, followed by an integer item which is the element to be inserted, separated by a space.2: Delete an element from the queue.3: Display the elements in the queue.4: Exit the program.Output format :The output displays the following format:For Insert Operation choice 1: If the queue is full, print "Queue Overflow". Otherwise, no output is generated for the insert operation.For Delete Operation choice 2: If the queue is empty, print "Queue Underflow". Otherwise, print "Element deleted from queue is: X" where X is the integer that was removed from the queue.For Display Operation choice 3: Print "Queue elements:" followed by the integers in the queue from front to rear.If the queue is empty, print "Queue is empty".Refer to the sample output for the formatting specifications.Code constraints :In this scenario, the given test cases will fall under the following constraints:The queue has a maximum capacity of 10 elements.The queue operations should be performed in a circular manner.The operations will be continuous until the exit choice (4) is selected.Sample test cases :Input 1 :1 111 221 3321 441 5534Output 1 :Element deleted from queue is: 11Queue elements:22 33 44 55 Input 2 :24Output 2 :Queue UnderflowInput 3 :-14Output 3 :Wrong choiceInput 4 :1 221 331 441 551 661 771 881 991 1001 1111 1224Output 4 :Queue Overflow
A queue is an abstract data type that maintains the order in which elements were added to it, allowing the oldest elements to be removed from the front and new elements to be added to the rear. This is called a First-In-First-Out (FIFO) data structure because the first element added to the queue (i.e., the one that has been waiting the longest) is always the first one to be removed.A basic queue has the following operations:Enqueue: add a new element to the end of the queue.Dequeue: remove the element from the front of the queue and return it.In this challenge, you must first implement a queue using two stacks. Then process queries, where each query is one of the following types:1 x: Enqueue element into the end of the queue.2: Dequeue the element at the front of the queue.3: Print the element at the front of the queue.Input FormatThe first line contains a single integer, , denoting the number of queries.Each line of the subsequent lines contains a single query in the form described in the problem statement above. All three queries start with an integer denoting the query , but only query is followed by an additional space-separated value, , denoting the value to be enqueued.ConstraintsIt is guaranteed that a valid answer always exists for each query of type .Output FormatFor each query of type , print the value of the element at the front of the queue on a new line.Sample InputSTDIN Function----- --------10 q = 10 (number of queries)1 42 1st query, enqueue 422 dequeue front element1 14 enqueue 423 print the front element1 28 enqueue 283 print the front element1 60 enqueue 601 78 enqueue 782 dequeue front element2 dequeue front elementSample Output1414ExplanationPerform the following sequence of actions:Enqueue ; .Dequeue the value at the head of the queue, ; .Enqueue ; .Print the value at the head of the queue, ; .Enqueue ; .Print the value at the head of the queue, ; .Enqueue ; .Enqueue ; .Dequeue the value at the head of the queue, ; .Dequeue the value at the head of the queue, ; .
