Operations on Simple Queues

So, we've learned what a Queue is and the key terminologies related to it. We're now ready to roll up our sleeves and start working with Simple Queues. Remember our coffee shop line? Let's think of our Simple Queue in the same way.

The primary operations that we can perform on a Simple Queue are: Enqueue (add an element to the end of the Queue), and Dequeue (remove an element from the front). There's also Peek or Front (get the value of the front item without removing it), and IsEmpty (check if the Queue is empty).
