Two Stack PDA | 2 Stack PDA for a^nb^nc^n | Automata Theory | TOC | TAFL | FLAT
In this video, we explain how to design a Two Stack Pushdown Automaton (2-PDA) to accept the language L = { aⁿbⁿcⁿ | n ≥ 1 }, which cannot be accepted by a single stack PDA.
💡 This topic is essential in Automata Theory and is frequently asked in competitive exams like GATE, UGC-NET, and university exams.
📘 Topics Covered:
✔ Why 1-stack PDA fails for aⁿbⁿcⁿ
✔ How 2-stack PDA works
✔ Step-by-step construction and transitions
✔ Visual simulation of the 2-stack PDA
