A Turing machine computes the same set of language
A Turing machine computes the same set of languages as a modified pushdown automaton with two of these; a standard pushdown automaton has only one. Recursive algorithms save environments to this [i] data structure in memory when they are invoked. Searches are O( n) [O of n],but pushes and pops take constant time in—for 10 points—what data structures, linked lists that obey last-in-first-out?
