Mar 25, 2025 · Implement a stack using queues. The stack should support the following operations: Push(x): Push an element onto the stack. Pop(): Pop the element from the top of the stack and return it. A Stack can be implemented using two queues. Let Stack to be implemented be 's' and queues used to implement are 'q1' and 'q2'.

May 22, 2024 · In C++, the std::stack is a container that follows the LIFO (Last In, First Out) rule, whereas std::queue is a container that follows the FIFO (First In, First Out) rule. In this article, we will learn how to create a stack of a queue in C++.

Dec 5, 2012 · If you really want to implement a queue using a stack you could add a Stack member variable to the Queue class. The methods are then implemented like this: void Queue::enqueue(int value) { stack.push(value); } int Queue::dequeue() { // TODO: …

Mar 28, 2025 · Given a stack that supports push and pop operations, your task is to implement a queue using one or more instances of that stack along with its operations. A queue can be implemented using two stacks. Let the queue be represented as q, and the stacks used for its implementation be s1 and s2.

We have to implement functionalities of a stack data structure using queue data structure. Queue is a FIFO – first in first out data structure. Stack is a LIFO – last in first out data structure. push() - insert a element at the top. pop() - removing element from the top stack. top() – …
