WebProblem 4 (3 Points) The following context free grammar generates the language of binary strings with the same number of 1s as 0s. S → λ. S → 0S1S. S → 1S0S. Devise a pushdown automaton that recognizes the same language. Below are some tests you can apply in JFLAP ( Click here to download them) Input. Result. WebComputer Science questions and answers. 1. Find a pushdown automaton for the language: L1 = {a^2n b^n n ≥ 0 } 2. Modify the PDA in the previous question to recognize the language: L2 = {a^2n b^n n ≥ 1 } 3. Modify the PDA in the previous question to recognize the language: L3 = {a^2n ccb^n n ≥ 1 }. For example, aaccb, aaaaccbb ∈ L3 4.

Recall that we can't do that just by writing ε as the stack character, since that always matches, even if the stack is not empty.
