Can someone help. thanks
question:
<exp> ::= <int>|<exp> <op> <exp>
<op>::= + | *
is ambiguous. Rewrite the grammar so that it accepts the same language unambiguous and honors the traditional interpretation of arithmetic expressions.
Using your grammar, provide a derivation of the expressions:
2*3+5*4 and 2+3*5*4
.
