The moves in the PDA is technically termed as: a) Turnstile ... Automata Theory Multiple Choice Questions & Answers (MCQs) Set-1. Pushdown Automata The PDA is an automaton equivalent to the CFG in language-defining power. Hence (B) is correct option. Not all context-free languages are deterministic. (A) Finite state automata (B) Deterministic pushdown automata (C) Non-deterministic pushdown automata (D) Turing machine. MCQ (Single Correct Answer) GATE CSE 2011 The lexical analysis for a modern computer language such as java needs the power of which one of the following machine model in a … This test is Rated positive by 92% students preparing for Computer Science Engineering (CSE).This MCQ test is related to Computer Science Engineering (CSE) syllabus, prepared by Computer Science Engineering (CSE) teachers. The language recognized by deterministic pushdown automaton is deterministic context free language. A DFA can operate on finite data, but a PDA can operate on infinite data. Explanation: A Deterministic Push Down Automata is a Push Down Automata in which no state p has two or more transitions. Lexical analyzers are typically based on finite state automata. February 26, 2018. In automata theory, a deterministic pushdown automaton (DPDA or DPA) is a variation of the pushdown automaton.The class of deterministic pushdown automata accepts the deterministic context-free languages, a proper subset of context-free languages.. Machine transitions are based on the current state and input symbol, and also the current topmost symbol of the stack. 14. A pushdown automata or pushdown automaton or PDA is a technique to implement a context−free grammar in a similar way we design Deterministic Finite Automaton or DFA for a regular grammar. The language accepted by a Pushdown Automaton in which the stack is limited to 10 items is best described as (A) Context free (B) Regular (C) Deterministic Context free (D) Recursive. A DFA can remember a finite amount of information, but a PDA can remember an infinite amount of information. Multiple choice questions on Theory of Computation(TOC) for UGC NET Computer science. SOLUTION. Here, take the example of odd length palindrome: A PDA is non-deterministic, if there are more than one REJECT states in PDA. Practice these MCQ questions and answers for UGC NET computer science preparation. ... Power of deterministic pushdown automata is equivalent to power of non-deterministic pushdown automata. Answer (A) Lexical analysis is the first step in compilation. Deterministic Push-down Automata. Pushdown automata is simply an NFA augmented with an "external stack memory". ... Finite Automata are less powerful than Pushdown Automata. In lexical analysis, program is divided into tokens. Most programming languages have deterministic PDA’s. The Deterministic Push-down Automata is a variation of push down automata that accepts the deterministic context-free languages.. A language L(A) is accepted by a deterministic push down automata if and only if there is a single computation from the initial configuration until an accepting one for all strings belonging to L(A). Only the nondeterministic PDA defines all the CFL’s. Hence, it is important to learn, how to draw PDA. Question # 8 of 10 (Start time: 05:55:36 PM) Total Marks: 1 ... PHP - Multiple Choice Questions (MCQs) - Objective Questions (1) PDA is a way to implement context free languages. Pushdown Automaton uses stock as data structure & languages accepted by PDA is regular. Jan 06,2021 - Test: Deterministic PDA | 10 Questions MCQ Test has questions of Computer Science Engineering (CSE) preparation. A Pushdown Automaton (PDA) is like an epsilon Non deterministic Finite Automata (NFA) with infinite stack. c. But the deterministic version models parsers.
