A Circular Queue is an advanced version of a linear queue where the last position connects back to the first, forming a circular structure. This implementation avoids the wastage of space seen in linear queues.
Below is the Python implementation of a circular queue using arrays, along with its operations.
class CircularQueue:def __init__(self, capacity):self.queue = [None] * capacityself.capacity = capacityself.front = -1self.rear = -1def enqueue(self, value):if (self.rear + 1) % self.capacity == self.front:print("Queue is full")returnif self.front == -1: # First element insertionself.front = 0self.rear = (self.rear + 1) % self.capacityself.queue[self.rear] = valueprint(f"Enqueued: {value}")def dequeue(self):if self.front == -1:print("Queue is empty")return Noneremoved_value = self.queue[self.front]if self.front == self.rear: # Queue becomes empty after this operationself.front = -1self.rear = -1else:self.front = (self.front + 1) % self.capacityprint(f"Dequeued: {removed_value}")return removed_valuedef display(self):if self.front == -1:print("Queue is empty")returnprint("Queue elements:", end=" ")i = self.frontwhile True:print(self.queue[i], end=" ")if i == self.rear:breaki = (i + 1) % self.capacityprint()# Demonstration of Circular Queue Operationscq = CircularQueue(5)cq.enqueue(10)cq.enqueue(20)cq.enqueue(30)cq.enqueue(40)cq.display()cq.dequeue()cq.dequeue()cq.display()cq.enqueue(50)cq.enqueue(60)cq.display()కాపీ చేయబడింది!✕కాపీ చేయి Implementation of Circular Queue Using Array - GeeksforGeeks
