Dataflow analysis

What is the maximum number of reduce moves that can be taken by a bottom-up parser for a grammar with no epsilon- and unit-production (i.e., of type A -> є and A -> a) to parse a string with n tokens?

N/2

N - 1

2n-1

2^n

An LALR(1) parser for a grammar G can have shift-reduce (S-R) conflicts if and only if

The SLR(1) parser for G has S-R conflicts

The LR(1) parser for G has S-R conflicts

The LR(0) parser for G has S-R conflicts

The LALR(1) parser for G has reduce-reduce conflicts

Which one of the following is a top-down parser?

Recursive descent parser

Operator precedence parser

An LR(k) parser

An LALR(k) parser

Consider the following two statements: P: Every regular grammar is LL(1) Q: Every regular set has a LR(1) grammar Which of the following is TRUE?

Both P and Q are true

P is true and Q is false

P is false and Q is true

Both P and Q are false

A canonical set of items is given below S --> L. > R Q --> R. On input symbol < the set has

a shift-reduce conflict and a reduce-reduce conflict

A shift-reduce conflict but not a reduce-reduce conflict

A reduce-reduce conflict but not a shift-reduce conflict

Neither a shift-reduce nor a reduce-reduce conflict

The grammar A → AA | (A) | ε is not suitable for predictive-parsing because the grammar is

Ambiguous

Left-recursive

Right-recursive

An operator-grammar

Consider the grammar S → (S) | a Let the number of states in SLR(1), LR(1) and LALR(1) parsers for the grammar be n1, n2 and n3 respectively. The following relationship holds good

N1 < n2 < n3

N1 = n3 < n2

N1 = n2 = n3

N1 ≥ n3 ≥ n2
