Give a PDA (Pushdown Automata) that recognizes the language L = {σ ∈ {x, y, z} ∗ | 2|σ|x = |σ|y ∨ 2|σ|y = |σ|z} You can choose whether your PDA accepts by empty stack or final state, but make sure you clearly note, which acceptance is assumed.
A B-bounded PDA (pushdown automaton) is a PDA M such that it crashes whenever its stack height reaches B. Show that the language {0n1n : n ≥ 1} can not be accepted by a B-bounded PDA for any B.

6. Consider a Pushdown Automata with TWO STACKS. Show that this machine is more powerful than a single stack PDA. (Use the language L = {a"\"c"which is not a CFL. Explain bow a two stack automata can accept this language.) HINT : Give a table representation of the 2PDA - it should have 7 columns : state, input, stack 1, stack 2, new state, stack 1 operation, stack 2 operation.
Construct PDA for the following language L = {w : 2 na (w) ≤ nb (w) ≤3 na (w)}
Construct a grammar that generates the following language, L = (anbn+mam | n, m = 0, 1, 2, ...). Construct a grammar that generates the following language, L = (a"bn-ma" n, m = O, 1, 2, ..)
