A sequence of natural numbers (a1, az,.., an) is said to be a degree sequence if there exists an undirected (simple) graph on vertices {v1, v2, , vn)such that deg(v) = ai for each i = 1, 2, .., n. If the sequence is a degree sequence, justify your answer by drawing a graph. a. 1s (2, 3, 3, 3, 3, 3, 3, 7) a degree sequence? Justify your answer. b. Is (3,
