Implementation of a stack using two queuesLikewise, a queue can be implemented with two stacks, a stack can also be implemented using two queues. The basic idea is to perform stack ADT operations using the two queues.So, we need to implement push(),pop() using DeQueue(), EnQueue() ...

Algorithm for the Implementation of Queue using Array For Insertion: Step 1: Get the position of the first empty space ( value of the rear variable) Step 2: Assign the new value to position the rear in an array if the queue is not full. Step 3: Increment the value of the rear variab...

Working of queue: We can implement queue by using two pointers i.e. FRONT and REAR. FRONT is used to track the first element of the queue. REAR is used to track the last element of the queue. Initially, we’ll set the values of FRONT and REAR to -1. ...
