2. Using the languages L1 and L2 from the previous problem, enumerate the first 6 strings in the L-ordering of the following. If there are fewer than 7 string, enumerate the entire language: a) Suff(L2) b) Pref(L1) c) h(L1) where h(0) = ab and h(1) = c, = {a, b, c}

3. What are the unique substrings of w = ccabca over = {a, b, c}?
