1. Give a formal definition of a two-tape Turing machine; then write programs that accept the languages below. Assume that = input is initially all on tape 1. {a, b, c} and that the (a) L= {ab}, n 1. (b) L= {abcm, m>n}. (c) L = {www {a, b}}. (d) L= {www: w {a,b}}. (e) L = (f) L = {na (w) = n(w) = nc(w)}. = {na(w) = n(w) nc(w)}. 1.
