4. (10 points total) Let (Mi), (M2), (Ms).. be an enumeration of all Turing machines with input alphabet 0, 1. Let w, w2, ws,…be an enumeration of all binary strings. Prove that D w|i> 0 and Mi does not accept wi) is not Turing-recognizable. Hint: Use contradiction-assume D is Turing-recognizable and then use diagonalization Show transcribed image text 4.
