Upon seeing a look ahead, if a production has a two different moves for same terminal then its a conflict.
If a state, after seeing a look ahead, points to another non final state, then its Shift move. If it points to final state, then its a reduce move. And if both takes place, then it's a SR conflict.
Now, in given question,
no such condition occurs, hence it's conflict free grammer, neither SR nor RR.
