For N = {1, 2, 3}, compute the bargaining set of the coalitional game (N; v) relative to the coalitional structure {{1, 2},{3}}, for each of the following coalitional functions:
(a) v(1) = v(2) = v(3) = 0, v(1, 2) = 40, v(1, 3) = 50, v(2, 3) = 60, v(1, 2, 3) = 100.
(b) v(1) = v(2) = v(3) = 0, v(1, 2) = 80, v(1, 3) = 20, v(2, 3) = 30, v(1, 2, 3) = 100.
