Build a grammar for a regular expression, where the 5 token types are: sym * or ( ) We are using or as the terminal that represents the union operator (|) to avoid conflict with common grammar notation and to emphasize that tokens are not in one-to-one correspondence with the input characters. Have your grammar be unambiguous and enforce the appropriate precedence. Use your grammar to parse the input (ax*|b)*d(ef)* i.e. the token stream: ( sym sym * or sym ) * sym ( sym sym ) * producing a parse tree with the lexemes for each sym shown
