Question: I tried to make a pushdown automaton that accepts the language L = {a i b j c k | i = j or i=k,
I tried to make a pushdown automaton that accepts the language L = {aibjck | i = j or i=k, i, j, k > 0} but it accepts the empty string and the language has i, j, k > 0 so it shouldn't accept an empty string. How do I need to change it so it fits the language above?
