(15pts) Toward a contradiction assume there exists a Turing machine H which when given as input the encoding for an arbitrary Turing machine, M, and an arbitrary imput string, s, can decide if M will halt, (ie, accept or reject), on input z or Loop. Then it would be possible to build a Turing machine IMP which could take its input string, s, and using the H machine coding as a subroutine determine if a machine, M. with control encoding, z, would Halt or Loop with z as input and then do the opposite. Show that machine IMP can not possibly exist. What does this prove
