Left factoring solved examples
Nettet13. jan. 2024 · I’ve already removed the left recursion, but I’m having trouble doing left-factoring. All of the examples I’ve found are simple, and look something like this: A -> aX aY becomes: A -> aZ Z -> X Y I understand that. However, my grammar looks more like this: X -> aE IXE (X)E E -> IE BXE ϵ I -> ++ -- B -> + - ϵ Nettetrepresents all alternatives for A -productions that do not start with .
