two context-free grammars G1 and G2 for generating a single C-like array

declaration. The dimension of the array is at least one. For example,

int a[10][3];

 The grammars use D

as the start

symbol, and use six terminal symbols int ; id [ ] num.

Grammar

G1                           Grammar G2

               D →

int

L;                                 D

               L→id [E                                     L→ id E

               E → num ]                                 E → E [num]

               E →num] [ E                             E → [num]

     Which of the grammars correctly generate

the declaration mentioned above?
