Describe a Turing machine (including an explicit state diagram) which, when started with a bit string on the tape with the tape head pointing at the first bit, will decrement the bit string, and then enter the accept state. If the bit string has no 1 bits (i.e., it represents 0), enter the reject state. (So, if we start with 1001100, the binary representation of 76, we should replace it with 1001011, the binary representation of 75.)
