Part (b) does not change, although the constructed TM will fail to accepting state following a path that is one longer than the paths xyz, where xz is also in L. We claim there are no strings in L of length 2n or more, and thus Note, however, that state H is inaccessible, so it should be represented by S. To complete the construction of B, we have only to specify: Suppose, however, that there are no strings in L whose length is in Basis: |w| = 1. D0(M) is the empty set [that's part (e)].
