- (IN C++) Write a program to implement Quicksort. Also implement one of the slow sorts (Bubble, Insertion...). After you have tested both, generate a very large array (30,000 or more) of bytes and sort increasingly larger portions of the array (5000, 10000, ..., 30000) with both algorithms. Draw a graph of execution time versus number of elements for both algorithms. What are your conclusions? (IN C++) please.Write a C++ program to implement quick sort for n elements. Then run the program with the following inputs: (a). an arbitrary input, (b). sorted input, (c). reverse-ordered input, (d). an input that all elements are equal. Please provide screenshots of the code, and the output of each (4) inputs. Total 5 screenshots.

- Develop a merging implementation based on the following idea to reduce the required extra space to max(M, N/M): For the purpose of simplicity, split the array into N/M blocks of size M and assume that N is a multiple of M. Following that, (i) use selection sort to order the blocks, treating them as items and using their first key as the sort key; and (ii) iterate over the array, merging the first block with the second, the second block with the third, and so on.

Develop a merging implementation based on the following idea to…To get the necessary excess space down to max(M, N/M), create a merging implementation based on the following concept: Divide the array into N/M blocks of size M in order to keep things simple, and assume that N is a multiple of M. The blocks are then (i) sorted using selection sort, which treats them as items and uses their first key as the sort key, and (ii) merged as the array is iterated through. The first block is merged with the second, the second block with the third, and so on.Language: C Implement the binary search algorithm, to find an integer in a sorted array. a) Declare an array of N integers. Use the preprocessor #define directive for the size of the array. Let the first element be 0. Fill the array, by assigning to each element the value of the previous element plus a pseudorandom, nonnegative number. b) Given a sorted array of N integers, write a function to recursively search for a given element x in and return the index of x in the array, or -1 if the element is not found. To this end, divide the interval into two halves. If the value of the element is less than the item in the middle of the interval, search further in the lower half of the interval, otherwise, search it in the upper half. c) Test your results, searching for randomly picked element from the array.
- code needed for python 3: You are required to investigate the number of comparisons that take place during the execution of an insertion sort. Given a list of ?N unsorted integers, use insertion sort to count the number of comparisons that it takes to arrive at the sorted list. Your insertion sort should execute from left to right. Function specifications Argument(s): integers (list) →→ a list of unsorted integers. Return: comparisons (int) →→ return the number of comparisons made to arrive at the sorted list. ### START FUNCTIONdef insertion_sort(integers): ### END FUNCTION integers = [15, 1, 2, 16, 12, 16, 9, 2, 0, 11]insertion_sort(integers.copy()) Expected output integers = [15, 1, 2, 16, 12, 16, 9, 2, 0, 11] insertion_sort(integers) == 25implement QuickSort of ints that sorts the numbers in the non-decreasing order and in c language Implement the rearrange function used for QuickSort using the O(n) time algorithm with two pointers. The function gets as input an array, and index of the pivot. The function rearranges the array, and returns the index of the pivot after the rearrangement. please write form as: int rearrange(int* A, int n, int pivot_index); 2, Implement the QuickSort algorithm. For n<=2 the algorithm just sorts the (small) array (smaller number first). - For n>=3 the algorithm uses the rearrange function with the pivot chosen to be the median of A[0], A[n/2], A[n-1]. write as form: void quick_sort(int* A, int n);Modified Recursive Binary Search • Write C++ program hw7.cpp that meets the following requirements: – First, write a recursive binary search function with the following prototype: int binarySearch(int array[], int first, int last, int value); – Now suppose we have a sorted array like this: int a[SIZE] = { 3, 5, 7, 9, 22, 22, 22, 22, 30, 35, 51, 52, 73 }; – Then the following statement int index = binarySearch(a, 0, SIZE-1, 22); – would return one of the indices that match the target value (22), and it could be index 4, 5, 6, or 7. – Now, your mission is to modify this recursive binary search function to always return the leftmost index when there are multiple indices that match the target value. Thus, in the above case, the function must return index 4. – If no match found, the function returns -1. – Write a main function that checks if your modified binary search function works as expected with at least 3 example arrays. – Note: your modified binary search function must ensure the…
- Write a C++ program to find the number of comparisons using binarySearch and the sequintial search algorithm as follows:Suppose list is an array of 1000 elements.1.1 Use a random number generator to fill list.1.2 Use any sorting algorithm to sort the list.1.3 Search list for some items as follows:a. Use the binary search algorithm to searcg the list. (You may need to modify the algorithm to count the number of comparisons.b. Use the binary search algorithm to search the list, switching to a sequentialsearch when the size of the search list reduces to less than 15. (Use the sequential search algorithm for a sorted list.)Print the number of comparisons for Questions 1.3a and b. If the item is found in the list, then print its position.Exercise 1 Given the following recursive version of selection sort:public void recursiveSelectionSort(int a[], int n, int index){if (index == n)return;int k = minIndex(a, index, n-1);if (k != index)swap(a, k, index);recursiveSelectionSort(a, n, index + 1);}minIndex is a separate function that finds the smallest value in the given array “a” from“index” to “n-1” index values.swap is a separate function that swaps elements in the given array “a” between theelements at index “k” and “index” respectively.Assuming these 2 functions work as expected, there may be an error with therecursiveSelectionSort code. Answer the following:1) Design your own set of 8 unsorted integers in an array2) Determine what the given code will produce with your array by describing what thearray looks like with each recursive instance of recursiveSelectionSort3) If the code does have an error, describe the error, where it is, and how you would fixitFor example, if you said your array was [4 2 3 1 5 6 7 8], then…Create three problem instances of size n is around 10, representing the best-case, worst-case and average-case for Radix Sort respectively.
