Question

Construct PDA for the following language

L = {w : 2 n_a (w) ≤ n_b (w) ≤3 n_a (w)}

Answer 1

Answer #1

Here is a solution to your problem.

This is a NPDA. Deterministic push down automata is very hard to make.

It would be clearer if you try to draw it.

Hope this helps.

Let ?= (a, b). The Language L = {w E ?. : na(w) < na(w)) is not regular. (Note: na(w) and nu(w) are the number of a's and 's in tw, respectively.) To show this language is not regular, suppose you are given p. You now have complete choice of w. So choose wa+1, Of course you see how this satisfies the requirements of words in the language. Now, answer the following: (a) What is the largest value of lryl?...
