The following BNF grammer describes a Pascal-like syntax for declarations:
<decl_list> -> <decl> ; <decl_list>
                          | <decl>
<decl> -> <identifier> : <type>
<type> -> integar
            | real
            | record <decl_list> end
<identifier> -> a | b | c

Using this grammer, give a parse tree and a leftmost derivation for the following sentence:

a : record b : integer; c : real end
