A group of n people are lying on the beach. The beach is represented by the real line R and the location of the i-th person is some integer x; € Z. Your task is to prevent people from getting sunburned by covering them with umbrellas. Each umbrella corresponds to a closed interval I = [a, a+ L] of length Le N, and the i-th person is covered by that umbrella if r; e I. Design a greedy algorithm for covering all people with the minimum number of umbrellas. The input consists of the integers x1,..., Xn, and L. The output of your algorithm should be the positions of umbrellas.
