Solution 1

Here is a Python implementation of the circular queue program:

class Queue:
    def __init__(self, k):
        self.k = k
        self.queue = [''] * k
        self.head = self.tail = -1

    def enqueue(self, data):
        if ((self.tail + 1) % self.k == self.head):  
            print("Queue is full\n") 
            return
        elif (self.head == -1):  
            self.head = self.tail = 0
            self.queue[self.tail] = data
        else:  
            self.tail = (self.tail + 1) % self.k  
            self.queue[self.tail] = data 
        print(f"Character {data} is enqueued.")

    def dequeue(self):
        if (self.head == -1):  
            print("Queue is empty\n") 
        elif (self.head == self.tail):  
            temp=self.queue[self.head]  
            self.head = -1
            self.tail = -1
            print(f"Dequeued Character: {temp}")
        else: 
            temp = self.queue[self.head] 
            self.head = (self.head + 1) % self.k 
            print(f"Dequeued Character: {temp}")

    def display(self):
        if(self.head == -1):  
            print("No elements in the Queue") 
        elif (self.tail >= self.head): 
            print("Characters in the queue are:",end=" ") 
            for i in range(self.head, self.tail + 1): 
                print(self.queue[i], end=" ") 
            print()
        else: 
            print("Characters in the queue are:",end=" ") 
            for i in range(self.head, self.k): 
                print(self.queue[i], end=" ") 
            for i in range(0, self.tail + 1): 
                print(self.queue[i], end=" ") 
            print()

queue = Queue(5)
while True:
    print("1. Enqueue\n2. Dequeue\n3. Display\n4. Exit")
    choice = int(input("Enter your choice: "))
    if choice == 1:
        data = input("Enter the character to be enqueued: ")
        queue.enqueue(data)
    elif choice == 2:
        queue.dequeue()
    elif choice == 3:
        queue.display()
    elif choice == 4:
        print("Exiting program")
        break
    else:
        print("Invalid option.")

This program creates a circular queue with a maximum size of 5. It provides options to enqueue a character, dequeue a character, display the queue, and exit the program. The program continues to run and provide these options until the user chooses to exit.

Solution 2

Here is a Python implementation of the circular queue program:

class Queue:
    def __init__(self, k):
        self.k = k
        self.queue = [''] * k
        self.head = self.tail = -1

    def enqueue(self, data):
        if ((self.tail + 1) % self.k == self.head):  
            print("Queue is full. Cannot enqueue.")
        elif (self.head == -1):  
            self.head = self.tail = 0
            self.queue[self.tail] = data
            print(f"Character {data} is enqueued.")
        else:
            self.tail = (self.tail + 1) % self.k  
            self.queue[self.tail] = data
            print(f"Character {data} is enqueued.")

    def dequeue(self):

            temp = self.queue[self.head]
            self.head = self.tail = -1
            print(f"Dequeued Character: {temp}")
        else:
            temp = self.queue[self.head]
            self.head = (self.head + 1) % self.k
            print(f"Dequeued Character: {temp}")

    def display(self):
        if(self.head == -1):  
            print("Queue is empty.")
        elif (self.tail >= self.head):  
            print("Characters in the queue are: ", end = "")
            for i in range(self.head, self.tail + 1):
                print(self.queue[i], end = " ")
            print()
        else:  
            print("Characters in the queue are: ", end = "")
            for i in range(self.head, self.k):
                print(self.queue[i], end = " ")
            for i in range(0, self.tail + 1):
                print(self.queue[i], end = " ")
            print()

queue = Queue(5)
while True:
    print("Enter your choice (1: Enqueue, 2: Dequeue, 3: Display, 4: Exit):")
    choice = int(input())
    if choice == 1:
        print("Enter the character to enqueue:")
        data = input()
        queue.enqueue(data)
    elif choice == 2:
        queue.dequeue()
    elif choice == 3:
        queue.display()
    elif choice == 4:
        print("Exiting program")
        break
    else:
        print("Invalid option.")

This program creates a circular queue with a maximum size of 5. It prompts the user to enter a choice for the operation to perform. If the user chooses to enqueue a character, the program asks for the character and attempts to enqueue it. If the queue is full, it prints a message. If the user chooses to dequeue a character, the program attempts to dequeue a character and prints it. If the queue is empty, it prints a message. If the user chooses to display the queue, the program prints the characters in the queue. If the user chooses to exit, the program prints a message and breaks the loop. If the user enters an invalid choice, the program prints a message.

Your task is to create a user-friendly character queue program to support her learning journey.

Implement a circular queue using an array. Provide the enqueue and dequeue operations. give the answer for 5 marks

Problem StatementYou 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 OverflowInput 5 :34Output 5 :Queue is empty
