Circular queue in Data Structure

The queue that we implemented using an array suffers from one limitation. In that implementation there is a possibility that the queue is reported as full (since rear has reached the end of the array), even though in actuality there might be empty slots at the beginning of the queue. To overcome this limitation we can implement the queue as a circular queue . Here as we go on adding elements to the queue and reach the end of the array, the next element is stored in the first slot of the array (provided it is free).

More clearly, suppose an array arr of n elements is used to implement a circular queue. Now if we go on adding elements to the queue we may reach arr(n-l). We cannot add any more elements to the queue since we have reached the end of the an-ay. Instead of reporting the queue as full, if some elements in the queue have been deleted then there might be empty slots at the beginning of the queue. In such a case these slots would be filled by new elements being added to the queue. In short just because we have reached the end of the array the queue would not be reported as full. The queue would be reported as full only when all the slots in the array stand occupied.

Queue as an array - Data Structure

Queue, being a linear data structure can be represented in various ways such as arrays and linked lists. Representing a queue as an array would have the same problem that we discussed in case of stacks. An array is a data structure that can store a fixed number of elements. The size of an array should be fixed before using it Queue, on the other hand keeps on changing as we remove elements from the front end or add new elements at the rear end. Declaring an array with a maximum size would solve this problem. The maximum size should be large enough for a queue to expand or shrink.

Stack as an array Data Structure

Stack contains an ordered collection of elements. An array is used to store ordered list of elements. Hence, it would be very easy to manage a stack if we represent it using an array. However, the problem with an array is that we are required to declare the size of the array before using it in a program. This means the size of an array should be fixed. Stack on the other hand does not have any fixed size. It keeps on changing, as the elements in stack are popped or pushed.

Though an array and a stack are totally different data structures, an array can be used to store the elements of a stack. We can declare the array with a maximum size large enough to manage a stack. As a result, the stack can grow or shrink within the space reserved for it.
