WebNov 28, 2013 · To convert to a PDA, we can start with the easy parts. Your alphabet is {a,b,c}, you'll need a state for the "ab" section, and one for the "c (b (b^x_i)" part. Let's call the first one state p and the second q. Your stack alphabet will be {bottom,A,C}. Bottom is simply the symbol that indicates we've reached the bottom of the stack.
