About AP's, analyze the following statements
Finite state machines often don't address the totality of problems, an example is when it is necessary to use arithmetic expressions. To meet this need, Stack Automata (AP) are used,
I. An AP is a state machine very similar to a Deterministic Finite Automata (AFD), but with the addition of a LIFO (Last in, First out) data structure. II. One of the examples of using an AP is in compilers of programming languages, in the stage of syntactic analysis of a code. III. There are deterministic and non-deterministic APs, and the non-deterministic ones have a much greater scope than the deterministic ones. IV. It is not necessary to mark an empty stack for an AP to work, because at the end of reading a string, if the AP is in a final state, it is because the stack is necessarily empty.
The following items are correct:
A) I, II, III
B) I, II, IV
C) I, III, IV
D) II, III, IV
E) I, II, III, IV
