Chapter 12, Problem 8PC
Array/File Functions
Write a function named arrayToFile. The function should accept three arguments: the name of a file, a pointer to an int array, and the size of the array. The function should open the specified file in binary mode, write the contents of the array to the file, and then close the file.
Write another function named fileToArray. This function should accept three arguments: the name of a file, a pointer to an int array, and the size of the array. The function should open the specified file in binary mode, read its contents into the array, and then close the file.

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.
