The following context-free grammar has s-rules. S J → JCB K → aJb | e CCC E KaKcc | B → bB | E B We want to build an equivalent CFG without any e-rule. 1. Since & is in the language generated by this CFG, you need to add a new start variable. Show the resulting CFG. 2. Give the list of nullable variable(s) other than the new start variable. 3. Use the algorithm we saw in class to build an equivalent CFG without e-rules other than from the new start variable.
