6. Answer: a Difficulty: Medium Section Reference: Understanding QuickSort After you partition the array, you need only to sort the left and right sides of the array. The middle element is automatically sorted. To sort the left array, use the expression QuickSort( numbers, left, pivotIndex - 1); to sort the right array, you should use the expression QuickSort(numbers, pivotIndex + 1, right)).: 16. You are developing a sorting algorithm that uses partitioning and comparison to arrange an array of numbers in the correct order. You write a method that partitions the array so that the items less than pivot go to the left side, whereas the items greater than pivot go to the right side. The partitioning method has the following signature: static int Partition (int[] numbers, int left, int right, int pivotIndex) Which of the following algorithms should you use to sort the array using the Partition method?

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
