225. Implement Stack using Queues Implement a last-in-first-out (LIFO) stack using only two queues. The implemented stack should support all the functions of a normal stack (push,top,pop, andempty). Implement theMyStackclass: void push(int x)Pushes element x to the top of the stack. i...
using namespace std; class Stack { queue<int>q; public: void push(int val); void pop(); int top(); bool empty(); }; void Stack::push(int val) { int s = q.size(); q.push(val); for (int i=0; i<s; i++) { q.push(q.front()); q.pop(); } } void Stack::pop(...
Another important aspect to consider when dealing with the queue stack problem is the time and space complexity of the implemented solution. It is crucial to analyze the efficiency of the implementation in terms of the time taken to perform enqueue and dequeue operations, as well as the space ...

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...

Resizable-array implementation of the Deque interface; have no capacity restrictions. Not thread-safe; Do not support concurrent access by multiple threads. Null elements are prohibited. Faster than Stack when used as a stack, and faster than LinkedList when used as a queue. ...
