Question

Using the method quickSort that sort array of objects into an ascending order. For example, 70 80 60 75 50 30 40 85 is an array of Integer object 
Answer the following questions:

a. What does the array look like after quickSort partitions it for the first time? (Show all
intermediate results.)
b. How many comparisons did this partition process require?
c. The pivot is now between two subarrays called Smaller and Larger. Will the position of this
particular element
change during subsequent steps of the sort? Why or why not?
d. What recursive call to quickSort occurs next? 

F aa A else /** Sorts an array into ascending order. Uses quick sort with median-of-three pivot selection for arrays of at least MIN_SIZE entries, and uses insertion sort for smaller arrays. */ public static <T extends Comparable<? super T»> void quickSort(T[] a, int first, int last) { if (last - first + 1 < MIN_SIZE) { insertionSort (a, first, last); } { // Create the partition: Smaller | Pivot | Larger int pivotIndex = partition(a, first, last); // Sort subarrays Smaller and Larger quickSort(a, first, pivotIndex - 1); quickSort(a, pivotIndex + 1, last); } }
