For each of the following subsets of $\left\{x_{7}, x_{6}, \ldots, x_{1}, x_{0}\right\}$, determine the subset that immediately follows it by using the base 2 arithmetic generating scheme:
(a) $\left\{x_{4}, x_{1}, x_{0}\right\}$
(h) $\left\{x_{7}, x_{5}, x_{3}\right\}$
(c) $\left\{x_{7}, x_{5}, x_{4}, x_{3}, x_{2}, x_{1}, x_{0}\right\}$
(d) $\left\{x_{0}\right\}$
