P2) Given grammar in BNF, answer the following questions (30 points) <stmt-list>→<stmt> | <stmt»; <stmt-list> (a) Rewrite the given grammar into a EBNF (b) Is the given gramm...
Given a CFG in BNF, (50 points) <stmt_list> → <stmt> | <stmt>; <stmt_list> <stmt> → <var> = <expr> <expr> → <var> + <expr> | <var> * <expr> | <var> <var> →a| b| c| d show a derivation for the given sentence a = b*c - d; b = d - a 2. show a parsing tree for a = b*c - d; b = d - a
Please answer the questions below: 7. Rewrite the following BNF grammar using the form of EBNF described on the bottom half of page 127 in Sebesta. <import_decl> → import <import_list> ; <import_list> → <package_list> | <package_list> . * <package_list> → <identifier> | <package_list> . <identifier> <identifier> → a | b | c Make the resulting grammar as simple as possible, but keep all four of the original nonterminals, which will now be named ImportDecl, ImportList, PackageList, and Identifier. (Note: There...
Given the following grammar
statement if-stmt | other | Ԑ
if-stmt if (exp) statement else-part
else-part else statement | Ԑ
exp 0 | 1
a) Draw a parse tree for the string
If (0) if (1) other else else other
b) What is the purpose of the two else’s?
I need the the diagram of the parse tree

Question Set 2 1. Given the following grammar dactor>-> ( <expr> ) a) What is the associativity of each of the operators? What is precedence of the operators? Show a leftmost derivation and parse tree for the following sentence: b) c) A-A(B(C A)) d) Rewrite the BNF grammar above to give precedence over and force to be right associative.
