2. For quick sort, explain what the worst possible complexity could be for running the sort, based on the value of the pivot element. What is it about the value of the pivot that makes this complexity occur?

Give an example input (6 elements) for quick sort which would result in worst case performance, (using the scheme of choosing the left-most element as the pivot).
Sorting Sort the following array using the quick sort algorithm: (4 Marks) a. 12 26 8 9 7 0 4 Pivot selection is defined to be the first element of each sub-list. Show the array before and after each quicksort round (when the array is partitioned after placing the pivot at its correct position). Also, clearly highlight the pivot in each partition b. Consider an unsorted array of integers of size n. Write a Java program to arrange the array...
THESE ARE TRUE/FALSE The best-time complexity for insertion sort is O(nlogn). The worst-time complexity for bubble sort is O(nlogn). A linked structure consists of nodes. Each node is dynamically created to hold an element. All the nodes are linked together to form a list. The time complexity for searching an element in a binary search tree is O(logn) The time complexity for inserting an element into a binary search tree is O(logn). In an AVL tree, the element just inserted...
Suppose running mergesort on a takes 54 seconds in the worst case to sort a list of size 2^(18) . Taking the time complexity to be of the form Cnlog(n) calculate C and thus calculate the maximum time it would take to sort a list of the size 2^20 .
A. What is the time complexity of Merge Sort? B. Explain why Merge Sort has the time complexity you listed above in Part A. Algorithm Quicksort (A, left, right) if (left < right) pivot Point = [(left+right)/2] 11 note central pivot i left - 1 ja right + 1 do do it i +1 while (i < A.size) and (A[i] SA[pivot Point]) do jj-1 while (j > i) and (A[il > A[pivot Point]) if (i <j) then swap (A[i], Aljl)...
please I need it urgent thanks algorithms
