Construct a TM that accepts the following languages.a. L12={a2nbn | n ≥1}b. L5 = {02^n | n ≥1 }. i.e., the occurrences of 0 is always powers of 2, means, every time, you can divide the resultant to 2, recursively.
Let's pretend that L1 is a recursive language. Let L2 and L3 be recursively enumerable but not recursive languages. Which of the following statements is unlikely to be correct? L2 – L1 can be enumerated in a recursive manner. L1–L3 can be enumerated in a recursive manner. L2 is enumerable in a recursive manner. L2 is enumerable in a recursive manner.
