Pda For A-ib-jc-k Where J I K Jun 2026

But that’s tricky: if we are in q1, top Z, we know we exhausted a’s. But still b’s may come — we go to q2 and read b’s.

aibjcka to the i-th power b to the j-th power c to the k-th power sequence . If , the stack will not be empty at the end. If pda for a-ib-jc-k where j i k

For every 'a' read, push a symbol (e.g., 'A') onto the stack. But that’s tricky: if we are in q1,

We push for ( a )’s, then push again for ( c )’s, then pop for ( b )’s. If , the stack will not be empty at the end

Similarly from (q_1): ( \delta(q_1, \varepsilon, X) = (q_2, X) ) (finished (c)’s, start (b)’s) ( \delta(q_1, \varepsilon, Z_0) = (q_2, Z_0) ) (no (c)’s, go to (b)’s)

He began to type, the clicking of the keys echoing the logic of the stack.

And from (q_2): (\delta(q_2, b, Z) = (q_2, YZ)) # push Y for first extra b (\delta(q_2, b, Y) = (q_2, YY)) # push Y for each extra b.
