The main stack operations are: push (int data):Insertion at top int pop():Deletion from top Implementing Queue using stack A queue can be implanted using stack also. We need two stacks for implementation. The basic idea behind the implementation is to implement the queue operations (enqueue,...
1. Which data structures can be used for queue implementation? An array, stack, or linked list can be used to implement a queue. Using an Array is the simplest way to implement a queue. 2. Which operation is used in the queue implementation? A queue is an object used to manipulate an...
