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 b
Stack implementation using two Queues: Here, we are going to implement a stack using two queues using C++. Submitted by Radib Kar, on September 26, 2018 Stack and Queue at a glance...Stack:The stack is an ordered list where insertion and deletion are done from the same end, top. The...

Array representation of queue which contains 5 elements along with the respective values of front and rear: The above figure shows the queue of numbers. Since, we didn’t perform any deletion in the queue. Therefore, the value of front will remain -1. However the value of rear increases by...
int size():Returns size of the stack Example: Let the elements inserted are 1, 2, 3, 4 Stack Implementation using Array In C++ Prerequisites: top variable An Array namely stack_array So to implement a stack with array what we need to do is to implement those operations. ...
A reference implementation of an efficient lock-free stack, with specialized variants for a variety of memory management strategies and bounded concurrency. ck_queue A concurrently readable friendly derivative of the BSD-queue interface. Coupled with a safe memory reclamation mechanism, implement scalable...
Stack Time Complexity For the array-based implementation of a stack, the push and pop operations take constant time, i.e. O(1). Applications of Stack Data Structure Although stack is a simple data structure to implement, it is very powerful. The most common uses of a stack are: To rever...
