merge sort irrespective of the order of the elements performs the same complexity that is O(N log N) because it divides and conquers without seeing the elements
whereas in quicksort we choose the pivot , in case of almost sorted elements , it follows the following recurrence
T(n)= T(n-1)+ O(n)
if we solve the recurrence we get T(n)=O(n2)

Consider a variation of Merge sort called 4-way Merge sort. Instead of splitting the array into two parts like Merge sort, 4-way Merge sort splits the array into four parts. 4-way Merge divides the input array into fourths, calls itself for each fourth and then merges the four sorted fourths. a) Give pseudocode for 4-way Merge sort. b) State a recurrence for the number of comparisons executed by 4-way Merge sort and solve to determine the asymptotic running time.
Modify the sorts (selection sort, insertion sort, bubble sort, quick sort, and merge sort) by adding code to each to tally the total number of comparisons and total execution time of each algorithm. E...
Modify the sorts (selection sort, insertion sort, bubble sort, quick sort, and merge sort) by adding code to each to tally the total number of comparisons and total execution time of each algorithm. Execute the sort algorithms against the same list, recording information for the total number of comparisons and total execution time for each algorithm. Try several different lists, including at least one that is already in sorted order. ---------------------------------------------------------------------------------------------------------------- /** * Sorting demonstrates sorting and searching on an...

HW58.1. Array Merge Sort You've done merge (on Lists), so now it's time to do merge sort (on arrays). Create a public non-final class named Mergesort that extends Merge. Implement a public static method int[] mergesort(int[] values) that returns the input array of ints sorted in ascending order. You will want this method to be recursive, with the base case being an array with zero or one value. If the passed array is null you should return null. If the...

11.3 0(N log,N) Sorts 11. A merge sort is used to sort an array of 1,000 test scores in descending order Which one of the following statements is true? a. The sort is fastest if the original test scores are sorted from smallest to largect b. The sort is fastest if the original test scores are in completely random order. The sort is fastest if the original test scores are sorted from largest to smallest c. The sort is the...

Please answer by mathematical language: An array of n elements is almost sorted if and only if every element is at most k spots away from its actual location. Assuming that you can only perform pairwise comparisons, formally prove that any algorithm which can sort almost sorted arrays must have running time Ω(n log k), You may assume that n is a multiple of k.

Write a program to merge two sorted arrays into a third array. Ask the user to enter the size of the two arrays. The length of array1 could be greater than, equal to or less than the length of array2. Fill both with random numbers 0-99. Sort both arrays as explained below. Write a method merge that takes the two arrays as arguments. The method returns a merged array with size equal to the size of both arrays combined. Note:...

1 Couting Sort You may have learned some sorting algorithms - such as bubble sort ad quicksort in CS 110 and CS 210. This homework is about counting sort. Let n be the number of elements to be sorted. Bubble sort and quicksort assume tha time, which one is larger and which one is smaller. They make no assumption on the values of the elements t we can...

Instead of splitting the array into two parts like Merge sort, 4-way Merge sort splits the array into four parts. 4-way Merge divides the input array into fourths, calls itself for each fourth and then merges the four sorted fourths. a)Implement 4-way Merge sort from Problem 4 to sort an array/vector of integers and name it merge4. Implement the algorithm in the same language you used for the sorting algorithms...
