Detailed Solution: Question 1

 Two sets are called disjoint if they have no elements in common i.e. RÇT=Æ.

Test: PDA-Acceptance By Empty Stack - Question 2

Which among the following is not a part of the Context free grammar tuple?

Detailed Solution: Question 2

The tuple definition of context free grammar is: (V, T, P, S) where V=set of variables, T=set of terminals, P=production, S= Starting Variable.

Test: PDA-Acceptance By Empty Stack - Question 3

A context free grammar is a ___________

Detailed Solution: Question 3

Context free grammar is the set which belongs to the set of context free grammar. Similarly, Regular grammar is a set which belongs to the the set of Context free grammar.

Test: PDA-Acceptance By Empty Stack - Question 4

 The closure property of context free grammar includes :

Detailed Solution: Question 4

Context free grammars are closed under kleene operation, union and concatenation too.

Test: PDA-Acceptance By Empty Stack - Question 5

Which of the following automata takes stack as auxiliary storage?

Detailed Solution: Question 5

Pushdown Automaton uses stack as an auxiliary storage for its operations. Turing machines use Queue for the same.

Test: PDA-Acceptance By Empty Stack - Question 6

Which of the following automata takes queue as an auxiliary storage?

Detailed Solution: Question 6

Pushdown Automaton uses stack as an auxiliary storage for its operations. Turing machines use Queue for the same.

Test: PDA-Acceptance By Empty Stack - Question 7

A context free grammar can be recognized by

Detailed Solution: Question 7

A linearly bounded automata is a restricted non deterministic turing machine which is capable of accepting ant context free grammar.

Test: PDA-Acceptance By Empty Stack - Question 8

A null production can be referred to as:

Detailed Solution: Question 8

 Null production is always taken as a string in computational theory.

Test: PDA-Acceptance By Empty Stack - Question 9

The context free grammar which generates a Regular Language is termed as:

Detailed Solution: Question 9

Regular grammar is a subset of Context free grammar. The CFGs which produces a language for which a finite automaton can be created is called Regular grammar.

Test: PDA-Acceptance By Empty Stack - Question 10

 NPDA stands for

Detailed Solution: Question 10

 NPDA stands for non-deterministic push down automata whereas DPDA stands for deterministic push down automata.
