Insertion sort
The algorithm is basically designed to organize and sort the array or list of elements in specific manner, that enables the system and user to get the final sorted array or a list of elements.
Generally, it prepares a new array or list and then starts inserting elements in its appropriate position by following specific manner in this new list. This new list is known as sorted list.
Example:
- 1. Developing a phonebook contact list by sorting the names alphabetically.
- 2. Sorting a list of integers numerically, etc.
Selection sort:
It is a simple sorting algorithm which basically specifies the manner in which a list or array should be sorted. Generally, each time it finds the minimum elements from the unsorted array and then positions them in an appropriate form or ascending order.
Each time after finding the minimum or smallest element it swaps the element with the leftmost element.

- Create a list of N random numbers (Integer) and put them into a list and sort the list using the List’s sort method. Randomly select a number from the list. Find the position of the number in the list using binary search and record the number of comparison that you have to make (c). Then plot c against N for N = 30, 50, 75, 100, 150, 200, 300, 400, and 500. Implement the KMP algorithm from scratch. Test it and plot c against n and m where n is the size of the text and m is the size of the pattern, for different values of n and m. Implement the Boyer Moore algorithm from scratch. Test it and plot c against n and m where n is the size of the text and m is the size of the pattern, for different values of n and m. Implement the Z algorithm from scratch. Test it and plot c against n and m where n is the size of the text and m is the size of the pattern, for different values of n and m.arrow_forwardWrite an algorithm that searches a sorted list of n items by dividing it into three sublists of almost n/3 items. This algorithm finds the sublist that might contain the given item and divides it into three smaller sublists of almost equal size. The algorithm repeats this process until it finds the item or concludes that the item is not in the list. Analyze your algorithm and give the results using order notation.arrow_forwardPython: Write a program that takes an integer list as input and sorts the list into descending order using selection sort. The program should use nested loops and output the list after each iteration of the outer loop, thus outputting the list N-1 times (where N is the size of the list). Ex: If the input is: 20 10 30 40 the output is: [40, 10, 30, 20] [40, 30, 10, 20] [40, 30, 20, 10]arrow_forward
- 35. A particular sorting algorithm takes integer list 10, 6, 8 and incorrectly sorts the list to 6, 10, 8. What is true about the algorithm's correctness for sorting an arbitrary list of three integers? A.The algorithm is correct. B.The algorithm is incorrect. C.The algorithm's correctness is unknown. D.The algorithm only works for 10, 6, 8.arrow_forwardSorting ascends if a list is empty or all items except the last are less than or equal to their successors. Define isSorted to return True if a list is sorted and False otherwise. (Hint: Loop through a list of length 2 or more and compare pairs of items left to right, returning False if the first item is greater.)

- Implement the following two sorting algorithms in a program called p3.py. Write two separate functions for these algorithms. Both functions must take a list of integers as the input parameter.1) Bogosort: first shuffle the list argument (i.e., randomize the positions of every element) and then check to see if the result is in sorted order. If it is, the algorithm terminates successfully and returns True, but if it is not then the process must be repeated.2) Bozosort: choose two elements in the list at random, swap them, and then check if the result is in sorted order. If it is, the algorithm terminates successfully and returns True, but if it is not then the process must be repeated.Write a main() function and call both sorting functions using the same list as their arguments. The list can be of any size (try a small list first). Does any of your algorithms terminate? If yes, count the number of iterations it uses to sort the list. Does it always use the same number of repetitions? If…arrow_forwardA list is given an = {6,2,-4,13,7} Answer the following questions. a. What is n in an? b. List all the steps of sorting this list using insertion sort. c. What is the output of this search? And what does it indicate?arrow_forwardGiven the unsorted list [6, 5, 4, 3, 7, 1, 2], show what the contents of the listwould be after each iteration of the loop as it is sorted using the following:a. Selection sortb. Insertion sortarrow_forward
- Quick 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_forwardChoose either bubble sort, selection sort, or insertion sort (your choice) This is an algorithm tracing activity, not a coding exercise. Do not post any code or code output. Demonstrate the sort algorithm as follows: Start with a random, unordered list of at least EIGHT elements. Show step by step how the list will be re-arranged into sorted order. For each pass: State which element is being placed (Insertion sort only). Detail all comparisons and swaps that occur. State which element is in the correct location at the end of the pass.arrow_forwardWRITE THE MAIN.CPP FOR THIS PROGRAM a.
