a. Consider the following Semantic rules: Now translate the following assignments:

i) y = a [ i ] [ j ] + b [ c [ k ] ] [ j ]

ii) y = c [ k ] + b [ a [ c [ i ] ] + 2 ]

B.Grammar:

A B a | c B b | d C b | d C a

B q | | A a C

C f A C B | q

Fill the CLR(1) parsing table with suitable error codes / messages and identify the error in the given input string: c b a f q q a c q
