Original question and givens
Use the complete finite nondeterministic PDA: states=[push16, pop16, accept16], input_alphabet=[a16, b16], stack_alphabet=[Z16, A16], start_state=push16, bottom_symbol=Z16, final_states=[accept16], transitions=[[push16, a16, Z16, push16, [Z16, A16]], [push16, a16, A16, push16, [A16, A16]], [push16, b16, A16, pop16, []], [pop16, b16, A16, pop16, []], [push16, null, Z16, accept16, [Z16]], [pop16, null, Z16, accept16, [Z16]]]. Alphabets are unique and pairwise disjoint. Each transition is [from,input symbol or null,required top,to,replacement bottom-to-top]. null is epsilon and consumes no input. Configurations are [state,input position,stack] with bottom first and top last. Preserve the bottom marker and accept only after consuming the entire input in a final state, not by empty stack. Give (states, input_alphabet, stack_alphabet, start_state, bottom_symbol, final_states, transition_count, qualified, convention).
