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...
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, dequeue) with stack operations (push, pop). Implementation: Let s1 and s2 be the two stacks used for implanting the queue...
publicvoidpush(intx) { while(!stack.isEmpty()){ aux.push(stack.pop()); } stack.push(x); while(!aux.isEmpty()){ stack.push(aux.pop()); } } // Removes the element from in front of queue. publicvoidpop() { stack.pop(); } // Get the front element. publicintpeek() { retu...
We can implement the queue in any programming language like C, C++, Java, Python or C#, but the specification is pretty much the same. Basic Operations of Queue A queue is an object (an abstract data structure - ADT) that allows the following operations: ...
Stack: Implements a stack akin to std::stack in C++. String: Implements a basic string class that mimics std::string in C++. Vector: Implements a dynamic array similar to std::vector in C++. PriorityQueue: Implements a priority queue based on std::priority_queue in C++. Deque: Implements...
A stack is a useful data structure in programming. It is just like a pile of plates kept on top of each other. In this tutorial, you will understand the working of Stack and it's implementations in Python, Java, C, and C++.

ck_stack 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, implemen...
