The format is a binary formatconsisting of a sign bit (negative = 1), a base 2, 8-bit,excess-128 exponent, and 23 bits of mantissa, withthe implied binary point to the right of the first bit ofthe mantissa.
Construct a TM M4 which accepts the language { w2w | w in {0,1}* }. This means, any input that comprises two copies of a binary string w separated by a single 2 symbol should be accepted. Any other input should be rejected. The input alphabet is {0,1,2}. The tape alphabet contains 0, 1, 2, _ and you may use additional symbols 3, 4, 9 if you wish (M4 can be constructed comfortably with just one additional symbol 3). The tape's content after M4 halts does not matter. Submit a representation of M4 as described above. ••*/
