... the running time to Θ(n log n). One could try to solve this problem from scratch using Divide&Conquer. A better approach is to notice that once the set is sorted, the problem becomes a lot easier. So assume that we start by sorting the set S into an array a in time O(n log n), say by using Merge Sor ...
