225. Implement Stack using Queues

LeetCodeStackDesignQueueOpen on judge ↗

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, and empty). Implement the MyStack class: - void push(int x) Pushes element x to the top of the stack. - int pop() Removes the element on the top of the stack and returns it. - int top() Returns the element on the top of the stack. - boolea
