Doubt regarding Viable prefix
I have one doubt regarding getting viable prefixes for a grammar. Suppose I am given a grammar G which is told to be LR(0).I have observed, if I draw LR(0) DFA for it, and see if there is a path labeled $\gamma$ from initial state to ... directly for LR(1)? I want a good process to give me viable prefix in a reasonable amount of time and accurate answer. Pleas help.
