Write a PDA (Pushdown Automaton) that accepts the language of strings over {a, b, c} where the number of instances of ab is equal to the number of instances of bc. This should be done in Mentor Formal Language for PDAs. This is what I currently have:
alphabet: {a, b, c}
start: q0
accepting: {q3}
// Initialization
q0(_,_-> $, q1)
// Track 'a' and 'b' for 'ab' sequence
q1(a,_-> A, q1)
q1(b, A -> X, q1)
// Track 'b' and 'c' for 'bc' sequence
q1(b,_-> B, q1)
q1(c, B ->_, q1)
// Manage other transitions
q1(a, X -> AX, q1)
q1(b, X -> X, q1)
// Handle 'b' followed by 'c'
q1(b, X -> B, q2)
q2(c, B ->_, q1)
// States to handle errors or reject
q2(_,_->_, q2)
// Final acceptance condition checking for balanced stack and empty input
q1(_, $ ->_, q3)
