Suppose n activities apply for using a common resource. Activity ai (1 ≤ i ≤ n) has a starting time S[i] and a finish time F[i] such that 0 < S[i] < F[i]. Two activities ai and aj (1 ≤ i, j ≤ n) are compatible if intervals [S[i], F[i]) and [S[j], F[j]) do not overlap. We assume the activities have been sorted such that S [1] ≤ S [2] ≤ …≤ S[n]. (a) Design an O(n2) dynamic programming algorithm...
