Types of Queue Data Structure
Queue data structure can be classified into 4 types:
There are different types of queues:
- Simple Queue: Simple Queue simply follows FIFO Structure. We can only insert the element at the back and remove the element from the front of the queue.
- Double-Ended Queue (Dequeue): In a double-ended queue the insertion and deletion operations, both can be performed from both ends. They are of two types:
- Input Restricted Queue: This is a simple queue. In this type of queue, the input can be taken from only one end but deletion can be done from any of the ends.
- Output Restricted Queue: This is also a simple queue. In this type of queue, the input can be taken from both ends but deletion can be done from only one end.
- Circular Queue: This is a special type of queue where the last position is connected back to the first position. Here also the operations are performed in FIFO order.
- Priority Queue: A priority queue is a special queue where the elements are accessed based on the priority assigned to them. They are of two types:
- Ascending Priority Queue: In Ascending Priority Queue, the elements are arranged in increasing order of their priority values. Element with smallest priority value is popped first.
- Descending Priority Queue: In Descending Priority Queue, the elements are arranged in decreasing order of their priority values. Element with largest priority is popper first.
Introduction to Queue Data Structure
Queue Data Structure is a linear data structure that follows FIFO (First In First Out) Principle, so the first element inserted is the first to be popped out. In this article, we will cover all the basics of Queue, Operations on Queue, its implementation, advantages, disadvantages which will help you solve all the problems based on Queue.
