Consider the language

                                                                        $L = \{ww:w\in\{a, b\}^+\}$.

Discuss the construction and efficiency of algorithms for accepting $L$ on

$\text(a)$ a standard Turing machine,

$\text(b)$ on a two-tape deterministic Turing machine,

$\text(c)$ on a single-tape nondeterministic Turing machine,

$\text(d)$ on a two-tape nondeterministic Turing machine.

Peter Linz Edition 5 Exercise 12.3 Question 1 (Page No. 317)
Let $A = \{001, 0011, 11, 101\}$ and $B = \{01, 111, 111, 010\}$. Does the pair $(A, B)$ have a PC solution$?$ Does it have an MPC solution$?$

Peter Linz Edition 5 Exercise 12.2 Question 1 (Page No. 311)
$\text{Theorem}:$ Let $M$ be any Turing machine. Then the question of whether or not $L(M)$ is finite is undecidable. Show in detail how the machine $\widehat{M}$ in $\text{Theorem}$ is constructed.
