WebFeb 23, 2024 · Odd length palindrome, String: a L does not contain any odd length string. Therefore, option 2 is false Option 3: a m b n n ≥ 0, m ≥ 0 String generated: a (n = 1, m = 0) L does not contain string: a. Therefore, option 3 is false Option 4: Even length palindrome Language L contains all even length palindrome. Therefore option 4 is correct WebMar 21, 2024 · To modify the PDA to accept the language of even-length palindromes, we need to ensure that the PDA only accepts palindromes with an even length. We can achieve this by adding a new state q1 and modifying the transitions as follows: Add a new transition from q0 to q1 for reading e (the empty string) on the stack and...
