Else if s > w, reject w" Since at most a ﬂnite number of strings of L are smaller than w in the desired ordering, so after a ﬂnite number of strings are printed by E, we can decide if w is in L or not. So,

WebSince the length of any string w ∈ B is odd, w must have a symbol exactly in the middle position; i.e., w = 2n + 1 for some n ≥ 0, and the (n + 1)th symbol in w is the middle one. If a string w of length 2n + 1 satisﬁes w = wR, the ﬁrst n symbols must match (in reverse order) the last n symbols, and the middle WebQuestion: Using induction on i, prove that 〖〖 (w〗^R)〗^i=〖〖 (w〗^i)〗^R for any string w and all i 0. Hints: feel free to use the following Theorem in your proof Let u,v∈Σ^*, then 〖 (uv)〗^R=v^R u^R. Using induction on i, prove that 〖〖 (w〗^R)〗^i=〖〖 (w〗^i)〗^R for any string w and all i 0. the baby-sitters club 2020
