8. In class we discussed how to write the syntax analysis functions for a recursive decent compiler. Using pseudo-code, write the Boolean function for the rule below. (Assume global variable \"lex\" contains the current token in input and there exists a function \"get\" which takes no arguments and returns the next token in the input. You do not need to give error messages) $\langle S \rangle$ ::= a $\langle T \rangle$ $\langle Y \rangle$ ::= $\langle X \rangle$ b Selection Sets $\{a\}$ $\{c, d\}$

Step 1
<S> =X>b =a<T><Y> This is a production rule that defines the non-terminal symbol <S> in terms of other symbols. It states that <S> can be replaced by the sequence "X>b =a<T><Y>". Show more…
