Implementation of Python Queue Conclusion What is Queue in Python? A queue is an abstract data type used for storing and managing data in a specific order. It has a rear (where elements are added) and a front (where elements are removed). Queues can be implemented using arrays or linked ...
Enqueue:This function is used to add an element to the rear end of the queue. If the queue is completely filled, then it will be in an overflow condition. The time complexity of the enqueue is O(1). Dequeue:This function is used to remove an element from the front end of the queue...
Array representation of queue which contains 5 elements along with the respective values of front and rear: The above figure shows the queue of numbers. Since, we didn’t perform any deletion in the queue. Therefore, the value of front will remain -1. However the value of rear increases by...
Queue Implementation using Two Stacks in C++: Here, we are going to implement a C++ program to implement Queue using two Stacks.
The complexity of enqueue and dequeue operations in a queue using an array isO(1). If you usepop(N)in python code, then the complexity might beO(n)depending on the position of the item to be popped. Applications of Queue CPU scheduling, Disk Scheduling ...

Working of Stack Data Structure Stack Implementations in Python, Java, C, and C++ The most common stack implementation is using arrays, but it can also be implemented using lists. Python Java C C++ # Stack implementation in python# Creating a stackdefcreate_stack():stack = []returnstack# Cr...
According to Official Python Docs, this module provides an implementation of the heap queue algorithm, also known as the priority queue algorithm. What is Heapify? The process of creating a heap data structure using the binary tree is called Heapify. The heapify process is used to create the ...
Peek:Returns the object at the front of the queue without removing it. IsEmpty:Tests if the queue is empty or not. Size:Returns the total number of elements present in the queue. Practice this problem Queue Implementation using an array: ...
