Lecture 4 Divide and Conquer Maximum/minimum Median finding
... number (the median corresponds to k = dn/2e). Given an array A[1, 2, . . . , n], one algorithm for selecting the kth smallest element is simply to sort A then return A[dn/2e]. This takes Θ(n log n) time using, say, MergeSort. How could we hope to do better? Well, suppose we had a black box that gave ...
