WebA pushdown automaton, PDA, is a collection of 8 things: 1. An alphabet Σ of input symbols. 2. An input TAPE (inﬁnite in 1 direction). The input word starts in the leftmost cell. The rest of the TAPE is blank. 3. An alphabet Γ of stack symbols. 4. A stack (inﬁnite in 1 direction), initially blank. 5. One START state that has only out-edges. 6.
