Scenario: You have a collection of 100 RANDOMIZED integers. Your program has a method called Find, which has one parameter, an integer value to search for. Of the options below, what would be the best strategy to maintain efficiency?
1. Binary Sort
2. Linear Search
3. Sort the Data using a Merge Sort, then use Binary Search
Is it better to utilize sequential search over binary search? What
are the advantages and disadvantages?

- A merge sort is used to sort an array of 1000 test scores in descending order. Which of the following statements is true?a) The sort is fastest if the original test scores are sorted from smallest to largestb) The sort is fastest if the original test scores are in completely sorted order.c) The sort is fastest if the original test scores are sorted from largest to smallest.d) The sort is the same, no matter what the order of the original elements.arrow_forwardTrue or false: In-place merge sort is a stable sort.arrow_forwardPlease answer the question in the screenshot. The language used is Java.arrow_forward
- What additional function is used in the Mergesort algorithm? Partition Search Merge Sortarrow_forwardWith the code given can you solve this questionarrow_forwardQuick Sort is another sorting algorithm that follows a divide-and-conquer approach. The algorithm can be summarized in 3 steps: A pivot element is chosen, usually the first element. All elements smaller than the pivot are placed to the left of the pivot. This creates 2 partitions, elements greater than the pivot and elements less than the pivot. The 2 partitions are sorted using Quick Sort. Sample code in python3: def quick_sort(arr): def quick_sort_r(arr, start, end): if end - start < 2: # single element base case return # choose a pivot pivot = start # you may choose other elements store = pivot+1 # index to store less than elements # for all elements after the pivot for i in range(pivot+1, end): if arr[i] < arr[pivot]: # if element is less than pivot arr[i], arr[store] = arr[store], arr[i] # swap store += 1 # increment store index # swap pivot with last element in less than…arrow_forward

Select one: a. greedy algorithm b. dynamic programming c. divide and conquer d. backtrackingarrow_forwardPlease answers fast Implement an external sort, which uses intermediate files to sort files bigger than main memory. Why Mergesort is a better algorithm than heapsort or quicksort to base such an implementation on? Test your program both on files with small records and on files with large records.arrow_forward
- What additional function is used in the QuickSort algorithm? Partition Merge Sort Searcharrow_forwardPerform a benchmark analysis of the following sorting algorithms: - Bubble Sort - Selection Sort - Insertion Sort - Shell Sort - Merge Sort - Quick Sort - Heap sort You can get source codes of sorting programs from lectures notes. By using the files that you generated in Question I, read each file and sort file by using each of sorting algorithms. Record the execution time of each sorting algorithm into a file named “sortStats.txt”. The “sortStats.txt” file should contain entries for execution times as follows: Bubble_Sort n1, n2, n3, n4, n5, n6, n7 Selection_Sort n1, n2, n3, n4, n5, n6, n7 Insertion_Sort n1, n2, n3, n4, n5, n6, n7 Shell_Sort n1, n2, n3, n4, n5, n6, n7 Merge_Sort n1, n2, n3, n4, n5, n6, n7 Quick_Sort n1, n2, n3, n4, n5, n6, n7 Heap_Sort n1, n2, n3, n4, n5, n6, n7 where n1, n2, n3, n4, n5, n6 and n7 are execution times for file sizes 1000, 5000, 10000, 25000, 50000, 100000, 20000.
