When sorting the following array in ascending order with quick sort:16 6 14 12 8 18 4 20 10if choosing the 4th element (i.e. 8) as the pivot, which of the following choices represents the array at one of the middle steps when partitioning the array?

A pivot element to partition unsorted list is used in a. Bubble Sort b. Merge Sort c. Quick Sort d. Selection Sort e. Binary Search

Consider a modification to QuickSort where each time the partition function is called, the median of the partition array is always found (in constant time) and used as the pivot. The worst-case running time for the algorithm is: Group of answer choices Θ(nlogn) Θ(n^2) Θ(n) Θ(logn)
