Question: We are given n items X = {x1, . . . xn}, m sets S1, . . . , Sm X, and an integer k.

We are given n items X = {x1, . . . xn}, m sets S1, . . . , Sm X, and an integer k. The goal is to find a family of k sets that maximizes the number of items covered, i.e. find S {S1, . . . , Sm}, |S| = k that maximizes | SS S|. Give a greedy algorithm that achieves 1 1/e approximation for this
