The following context-free grammar has an e-rule. SaXbY Za X Xa | Y |b Y YbY aZ | XX | E Z SS baa We want to build an equivalent CFG without any e-rule. in the language generated by this CFG, we don't need to variable.) 1. Give the list of nullable variable(s). (Since e is not add a new start 2. Use the algorithm we saw in class to build an equivalent CFG without e-rules.
