Which of the following statements is false?
  • a)
    An unambiguous grammar has same leftmost and rightmost derivation
  • b)
     An LL(1) parser is a top-down parser
  • c)
    LALR is more powerful than SLR
  • d)
    An ambiguous grammar can never be LR(k) for any k
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Which of the following statements is false?a)An unambiguous grammar ha...
(A) We can not have different Left Most Derivation and Right Most Derivation parse trees BUT we can certainly have different LMD and RMD for a given string.(LMD and RMD here refers to the order of various productions used for derivation which could be different.)
(D) is wrong w.r.t. question because IT IS TRUE that any LR(k) IS NEVER AMBIGUOUS and so an ambiguous can never be an LR(K) for any k, no matter how large k becomes.
(B) and (C) can not be the answer because LL(1) is TOP-DOWN parser and LALR is powerful than SLR. So both are TRUE.
