There is a unique decision tree T for quicksort on five element a_1, a_2, a_3, a_4, a_5. Draw the portion of the tree T showing the path from the root node to the leave node < a_5, a_4, a_3, a_2, a_1 >. For each node, you need to show the comparison made. For each edge, you need to label it with either YES or NO.

Walk through the operation of QuickSort when n = 7 and the input array is A = (11, 13, 12, 32, 31, 33, 20). (a) Count the number of comparisons in the walk through. using LAST ELEMENTS (LAST ANSWER WAS NOT USING LAST ELEMENT AS PIVOT) (b) Evaluate 7!, lg(7!) and 7 x lg(7). (c) Construct a best-case example for QuickSort with n = 15.

POLJOPP 3. Consider QuickSort on the array Aſlanand assume that the pivot element x (used to split the array Allo:hil into two portions such that all elements in the left portion Allom) are sx and all elements in the right portion Aſm:hi) are >x) is the last element of the array to be split (i. e., A[hi]). For a specific value of n at least 11 (your choice), construct an assignment of the...

(Quicksort) Here is an array which has just been partitioned by the first step of quicksort: 3, 0, 2, 4, 5, 8, 7, 6, 9. Which of these elements could have been the pivot? (List all possibilities and explain your answers.)

(5 marks; questions to Reza) In Lecture 5, Travis said you can prove QuickSort takes N(n log n) time in the best case the same way he proved any comparison-based sorting algorithm takes (n log n) time in the worst case. Give that proof. Notice it doesn't follow directly: e.g., Insertion Sort takes O(n) time in the best case. You can assume QuickSort divides each array into elements less than or equal to the pivot (including the pivot itself) and...

Someone help please Let A be an array of 5 integers, whose contents are as follows: 3, 2, 1, 5, 4 We will apply quick sort to sort this array. Show all of the element-wise comparisons made by the algorithm in the correct order. Here an element-wise comparison means the comparison of one element of the array with another element of the array or the key set in a particular step of the algorithm. Since the algorithm may move the...

Suppose the quicksort program shown uses a partition function that always picks a[m] as the 5B. 2M separator v. When the array a[m],....a[n] is reordered, assume that the order is preserved as much as possible. That is, first come all the elements less than v, in their original order, then all elements equal to v, and finally all elements greater than v, in their original order. int a[11]; void readArray0 {/* Reads 9 integers into int I; void quicksort( int...

Draw the recursion tree when n = 8, where n represents the length of the array, for the following recursive method: Determine a formula that counts the numbers of nodes in the recursion tree. What is the Big-Phi for execution time? Determine a formula that expresses the height of the tree. What is the Big-Phi for memory? Write an iterative solution for this same problem and compare its efficiency with this recursive solution.
