WebThe way that quicksort uses divide-and-conquer is a little different from how merge sort does. In merge sort, the divide step does hardly anything, and all the real work happens in the combine step. ... Use the median of medians method to select a pivot Pros: The pivot is guaranteed to be good. Quick sort is now O(n log n) worst case ! WebDivide and Conquer 6 This method is called “divide-and-conquer”. We have already seen a prototypical “serious” algorithm designed using such a method: the Merge-Sort. We split the array into two, sort the two parts recursively and then merge the two sorted arrays. We now look at a closely related but more interesting problem of counting inversions in an array.
