I have difficulty / doubt in transforming a grammar into LL (1), I tried remove left recursion but grammar still not LL(1).
S → SAB | abA | baC A → aSb | d B → bSaC| c C → cCd | b
Without left recursion
S - > abAS' | baCS' S ' ABS'| ε A → aSb | d B → bSaC| c C → cCd | b
After removing the left recursion I have a FIRST / FOLLOW SET CONFLICTS on production (S' -> ε) but if I remove the epsilon production I go into a "loop". What am I doing wrong?
