Consider the NPDA 〈Q = {q0, q1, q2}, Σ = {0,1}, Γ = {0,1,⊥}, δ, q0, ⊥, F = {q2}〉, where (as per usual convention) Q is set of states, Σ is the input alphabet, Γ is the stack alphabet, δ is the state transition function, q0 is the initial state, ⊥ is the initial stack symbol, and F is the set of accepting states.
