In this video, we are going to start a new topic: Queues

Like Stack data structure, Queue is also a linear data structure that follows a particular order in which the operations are performed. The order is First In First Out (FIFO), which means that the element that is inserted first in the queue will be the first one to be removed from the queue. A good example of queue is any queue of consumers for a resource where the consumer who came first is served first.

Operations on Queue: Mainly the following four basic operations are performed on queue:

Enqueue: Adds an item to the queue. If the queue is full, then it is said to be an Overflow condition.

Dequeue: Removes an item from the queue. The items are popped in the same order in which they are pushed. If the queue is empty, then it is said to be an Underflow condition.

Front: Get the front item from queue.

Rear: Get the last item from queue.




In this video, you’ll also learn about asymptotic notations, they are basically mathematical notations which represent order of growth of any mathematical function. There are three famous notations which you’ll see in this video, they are big O , Theta , Omega.

Welcome to the first video Tutorial on Data Structures And Algorithms. In this video I am going to provide an Introduction to Data Structures And Algorithms. This Course is created to Explain the Fundamentals of data structures and algorithms. This video Will explain What is data?, What is data structure?, The Need for Data Structures, What is algorithm?
