Consider the following grammar for Pascal variable declarations:

var-decl ! var decl-list

decl-list ! decl ; decl-list

decl-list ! decl

decl ! id-list : id

id-list ! id-list , id

id-list ! id

Indicate any problems in this grammar that prevent it from being parsed by a recursive-descent parser

with one token lookahead.

Transform this grammar into a form that can be parsed with a recursive-descent parser with one token

lookahead. Make as few changes to the grammar as possible. Do not use Extended BNF.
