Write a method called expunge that accepts a stack of integers as a parameter and makes sure that the stack’s elements are in nondecreasing order from top to bottom, by removing from the stack any element that is smaller than any element(s) on top of it. For example, if the stack stores [4, 20, 15, 15, 8, 5, 7, 12, 3, 10, 5, 1], the element values 3, 7, 5, 8, and 4 should be removed because each has an element above it with a larger value. So your method should change the stack to store [20, 15, 15, 12, 10, 5, 1]. Notice that now the elements are in nondecreasing order from top to bottom. If the stack is empty or has just one element, nothing changes. Use one queue or stack (but not both) as auxiliary storag
