We are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.

Consider the following Turing Machine (TM). Does the TM halt if it begins on the empty tape? If it halts, after how many steps? Does the TM halt if it begins on a tape that contains a single letter A followed by blanks? Justify your answer.
