Business Patterns are beneficial concepts. The queue is one of them that is used in nearly any business today, especially in call centers. You remember this when you hear some music and an iron voice telling you:

Why are queues so important, and what do they solve for your business?

Christopher Alexander is “the father” of the pattern language, a book describing a common-sense building approach using patterns. In this book, he elaborates 253 building patterns, solutions for problems that repeatedly occur in our environment. Once such a solution seems to work, it can be used many times

In business, there are also many patterns, and these are useful because they help you solve issues where others have been dealing with before.

Understanding with examples

An example of such a pattern is in the queue.

The idea behind a queue is not to let people wait but to organize activities most efficiently. There are many examples:

  • The line that is used in the call center
  • The queue where this article ends after I have submitted it
  • The queue for clients waiting for a medical treatment
  • The queue in front of the post office

The more efficient the organization behind the queue, the shorter the queue. If there hadn’t been a queue, the organization would be inefficient. The person would be waiting for clients to show up, and that costs money. When the queue grows out of proportion, the organization can no longer handle the number.

What solves the queue?

The queue solves the resource organization behind the queue. Once you have set up a queue, you can analyze queue “entries” and find different requests your organization needs different specialists or resources.

One of the fastest and most cost-effective methods for a company to improve operational efficiency and extract more income from current real estate is to have an efficient and well-managed queue. Because of its proven ability to reduce customer walk-away, increase revenue per square foot, stimulate impulse sales, and improve the overall customer experience, queue management – the process of efficiently moving customers in, through, and out of waiting for lines – is quickly becoming an essential element of best practices in many industries.

Data Structure for Queues

You will learn what a queue is in this lesson. You’ll also discover queue implementations in C, C++, Java, and Python. In programming, a queue is a proper data structure. It’s comparable to the ticket line outside a movie theatre, where the first person to join the line receives the first ticket.

The First In First Out (FIFO) rule applies to the queue: the item that goes in first comes out first. Queue representation based on the first-in-first-out principle

Queue Representation in FIFO

Because one was maintained in the line before 2, it is also the first to be withdrawn from the queue in the above picture. It adheres to the first-in, first-out (FIFO) principle. Enqueue is the programming word for adding things to a queue, while dequeue is the term for removing items from a queue.

The queue may be implemented in any programming language, including C, C++, Java, Python, and C#, but the definition remains the same.

Basic Queue Operations

A queue is an object (sometimes known as an abstract data structure or ADT) that enables you to perform the following operations:

  • Add an element to the end of the queue by enqueuing it.
  • Remove an element from the front of the queue by dequeuing it.

IsEmpty

Determines whether or not the queue is empty.

IsFull

Make sure the line isn’t too long.

Peek

Get the value of the queue’s front without taking it away.

Queue’s Operation

The following is how to queue operations work:

  • Two pointing devices REAR AND FRONT
  • FRONT keeps track of the queue’s initial item.
  • REAR follows the queue’s last element.
  • Set the value of FRONT and REAR to -1 at first.
  • Operation Enqueue
  • Make sure the queue isn’t too long.
  • Set the value of FRONT to 0 for the first element.
  • REAR index should be increased by one.
  • REAR is pointing to a new element, so place it there.
  • Operation of Dequeue
  • Make sure the queue isn’t complete.
  • FRONT points to a value that is to be returned.
  • One rise in the FRONT index
  • Set the values of FRONT and REAR for the final element.

Conclusion

Virtual queuing is the way for minimizing the line and hassle process,
