Depending on your language, queue may not be supported natively. You may simulate a queue by using a list or deque (double-ended queue), as long as you use only standard operations of a queue. You may assume that all operations are valid (for example, no pop or top operations will be...

Implement the following operations of a queue using stacks. push(x) -- Push element x to the back of queue. pop() -- Removes the element from in front of queue. peek() -- Get the front element. empty() -- Return whether the queue is empty. 1classMyQueue {23privateStack<Integer>s...

How to implement the Stack using a Single Queue? The Stack can be easily implemented by making the insertion operation costly. For the push operation i.e. the insertion operation, we will store the count of the elements (n) present in the stack. Then, the new element is inserted at the...
We can also implement a Stack using Queue in the below program. Example import java.util.*; public class StackFromQueueTest { Queue queue = new LinkedList(); public void push(int value) { int queueSize = queue.size(); queue.add(value); for (int i = 0; i < queueSize; i++) {...
