" These structures are Last In-First Out, and they come with "push" and "pop" operations.
The Java Virtual Machine is typically said to have an architecture based on this structure. With finite state machines, these structures are used in a variety of automata called PDAs. A memory location named after this structure grows downward and is used as function scratch space, in contrast to the (*) heap. Reverse Polish, or postfix, notation for arithmetic usually uses these data structures, and an excess of recursive calls often leads to their "overflow." These structures are Last In-First Out, and they come with "push" and "pop" operations. For 10 points, name these data structures usually contrasted with queues.
