To learn about Circular Queue, you should first have a good understanding of the following: 1. Queue is useful in CPU scheduling, Disk Scheduling. If the queue is empty(means S1 is empty), directly push the first element onto the stack S1. Experience. Queue is an example of a FIFO data structure. Example. Writing code in comment? Then add the new element to the first … How to implement a queue using two stacks? Following steps will be involved while enqueuing a new element to the queue. Once a new element is inserted into the Queue, all the elements inserted before the new element in the queue must be removed, to remove the new element. Queues are common in computer programs, where they are implemented as data structures coupled with access routines, as an abstract data structure or in object-oriented languages as classes. Living up to its name, a queue is very similar to standing in line for something: The person standing at the front of the line is the first one to have shown up, and they are the first ones to leave as well.

How easy it is to actually track another person credit card? Suppose a circular queue of capacity (n – 1) elements is implemented with an array of n elements. Assume that the insertion and deletion operation are carried out using REAR and FRONT as array index variables, respectively. Queue is a linear data structure where the first element is inserted from one end called REAR and deleted from the other end called as FRONT. VisuAlgo was conceptualised in 2011 by Dr Steven Halim as a tool to help his students better understand data structures and algorithms, by allowing them to learn the basics on their own and at their own pace.
