Splet29. apr. 2015 · Construct a PDA for the complement of a n b n c n (1 answer) Closed 7 years ago. I'm having trouble constructing a Context Free Grammar for the following language: a ∗ b ∗ c ∗ − { a n b n c n ∣ n ≥ 0 } I believe it's telling me that no string can be generated that has the same number of of a 's b 's and c 's. Splet03. jan. 2024 · Here we will see how to make a Turing machine for language L = {0n1n2n n ≥ n}. So this represents a kind of language where we will use only three characters 0s, 1s and 2s. The w is a string. So if w = 000111222, The Turing machine will accept it. To solve this, we will use this approach.
