Provide a method with signature transfer(S, T) that transfers all elements from stack S onto stack T. After transfer, S and T will contain the same set of elements in the same order. The element that at the top of S is the element that at the top of T. (Pseudo code is good enough. You can directly use the method isEmpty(), push(), pop(), top(), size() defined in Stack class. Temporary queue or stack can also be used in the middle if there is a need)
