    Solution Preview

    The worst case for Quicksort depends on the selection of the pivot element. Normally, if the first or the last element is chosen then there is a danger that the all the rest of the numbers need to be moved to the other side of the pivot and this happens recursively. In other words, the worst-case occurs when the input is already sorted. Since, many real-life inputs are nearly sorted, quicksort might perform worse ...
