A Pushdown Automaton (PDA) is a 7-tuple: M = (Q, Σ, Γ, δ, q₀, Z₀, F) --- Language: L = { w ∈ {0,1} 0(w) = 1(w) } Idea: Use the stack to track the difference between counts of 0s and 1s. - Push a symbol when one character is in excess. - Pop when the opposite character is read. - Accept when the s...
