Exercise D Implement the function isSorted that tests if a list is sorted or not NOTE you can use this with Quickcheck to test your mergSort function by calling quickCheck (sortProp . mergeSort) sortProp :: (Ord a) => [a] -> Bool sortProp xs = error "TODO implement sortProp"
desingn and implement parallel sort algorithm using MPI An array of given size is to be sorted. The size, the type of array and type of sort technique should be considered optional
Rank SortWrite an efficient parallel program that reads n integers from any input file and implements rank sort using p processors (p << n). Assume n is divisible by p.Given n integers stored in an array, rank sort computes rank of every a[j] as follows: Rank a[j] = no. of array elements that are ≤ a[j] for k = 0, 1, 2 … j-1 + no. of array elements that are < a[j] for k = j+1, j+2, j+3,… n – 1 Note: Every a[j] is compared with all array elements.
Arrange the given integer values in increasing order by applying step by step quicksort algorithm with following conditions: (a) Always choose first element of the list as pivot. (b) Do not assume infinity or maximum element at the end of the list during sorting. Given Data: 15, 11, 13, 14, 10, 8, 7, 9, 3, 5 (Initially, Pivot=15).
detailed answer plz
Not one of the optimised bubble sort's benefits over other sorts for sorted items. a) Quicker Reduced memory usage b) Input sorting is verified. Time is saved.

Python help. Using ( Heapq ) sorting algothrim create only one function def sortstring(filename): that takes in a file which has a bunch of sentences, each line of sentence consting of different length. Sort the setences from the lower length senteces to the highest length sentence. Print it after ( DON'T USE ANY SORTING BULT-IN FUNCTION ). Note: Keep note of time complexity as it should be able to run few 10,000 lines of sentences in few seconds.

Q: Modify the following algorithm of Merge Sort in such a way that during every recursive call it should divide the array into three partitions instead of two. What will be effect of this modification on the running time of Merge Time? Merge-Sort (A, left, right) if left ≥ right return else middle ← (left+right)/2 Merge-Sort(A, left, middle) Merge-Sort(A, middle+1, right) Merge(A, left, middle, right) Merge(A, left, middle, right) n1 ← middle – left + 1 n2 ← right – middle create array L[n1], R[n2] for i ← 0 to n1-1 do L[i] ← A[left +i] for j ← 0 to n2-1 do R[j] ← A[middle+j] k ← i ← j ← 0 while i< n1 & j< n2 if L[i] < R[j] A[k++] ← L[i++] else A[k++] ← R[j++] while i< n1 A[k++] ← L[i++] while j < n2 A[k++] ← R[j++]
