Solution

Answer:

S ---> aSA | epsilon

A ---> abS| c

We have to check the First/First Conflict and First/Flow Conflict

In the grammer above , there is no first/first conflict as we cannot see any single productions in the grammar.

But there is First/Flow conflict

As if we see a , we cannot decide what production to choose , whether we choose S--->aSA |epsilon or A ---> abS |c , but since we have epsilon production , it cannot have first/follow conflict , thus the grammar is LL(1).
