LL(1) Grammar Verification and Recursive Descent Parser Implementation
Consider the grammar $ G(S) $:
$ S \rightarrow AB $
$ A \rightarrow Da \mid \varepsilon $
$ B \rightarrow cC $
$ C \rightarrow aADC \mid \varepsilon $
$ D \rightarrow b \mid \varepsilon $
To determine if this grammar is LL(1), compute the necessary FIRST, FOLLOW, and SELECT sets:
$ \text{FIRST}(Da) = {b, a} $
$ \text{FIRST}(\varepsilon) = {\ ...
