Question: 5. Let L-(M) M is a DFA that accepts some string which is a palindrome (a) Show that L is Turing-recognizable Answer: (b) The solution

5. Let L-(M) M is a DFA that accepts some string

5. Let L-(M) M is a DFA that accepts some string which is a palindrome (a) Show that L is Turing-recognizable Answer: (b) The solution given to Problem 2.18 in the textbook proves that if C is a context-free language and R is a regular language then the language Cn R is context free. Use this along with the theorems in Section 4.1 to show that L is decidable
