Given the below array of integers, assume that quicksort chose the value '12' as the pivot value. Assuming we want to sort in ascending order, why is this a poor choice?
int a[] = { 6, 12, 8, 2, 1, 7 };
Group of answer choices:
it is the highest value in the array
it is near the median value of the array
it is less than 100
It is at the second position of the array
Homework Answers
OptionA
It is poor choice because, it is the highest value in the array, which makes unsorted array size to n-1.
It makes the complexity to O(n2) . Like selection sort or bubble sort, in each iteration one element is moved to right location.

HW60.1. Array Quicksort You've done partition so now it's time to finish Quicksort. Create a public non-final class named Quicksort that extends Partitioner. Implement a public static method void quicksort (int] values) that sorts the input array of ints in ascending order. You will want this method to be recursive, with the base case being an array with zero or one value. You should sort the array in place, which is why your function is declared to return void. If...
