6. Find a PDA for the language: L6 = {a^n b^p c^m | n = m or p = m, n, m, p ≥ 0 }.
Added by Emily A.
Step 1
First, we need to check if n = m or p = m. We can do this by pushing a symbol onto the stack for each a and c we read, and popping a symbol for each b we read. We can also push a special symbol onto the stack when we start reading b's, to keep track of whether we Show more…

Prove that the following language is decidable: ONE = {⟨P⟩ | P is a PDA with a single active accept state} Here, we say that a PDA has a single active accept state if: • The PDA does accept some strings. • All accepting computations end up in the same state.
