Here is a possible code example of how to implement a stack and queue using one array in Java. The array size is 10, and the stack and queue can store up to 5 elements each.

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: ...

You may simulate a stack by using a list or deque (double-ended queue), as long as you use only standard operations of a stack. You may assume that all operations are valid (for example, no pop or ...
