Merge sort

Merge Sort recursively sorts a given collection of numbers or elements by using the divide and conquer strategy in less time. It is one of the most used algorithms, with the worst-case time complexity of O (n log n). It was invented by John Von Neumann. The algorithm continuously divides an array into sub-arrays until each sub-array consists of a single element. It then merges those sub-arrays to produce a sorted array.

Assume you were to select the quicksort pivot as the middle element of the array. What are the two sub-arrays to be sorted that result after one iteration of quicksort? 30, 50, 20, 10 | 90, 100 10, 20, 30, 50 | 90, 100 30, 50, 20, 10 | 100, 90 30, 20, 50, 10 | 100, 9
You are running radix sort (base 10) on values 123, 322, 311, 332, 312, 132, 213, 321, 323. Unfortunately, the counting-sort implementation that your radix-sort calls is "anti-stable", that is, in case of a tie, it always reverses the order of two keys. What is the final order you get? Show the array after each pass.
Modify the FindBestPlan(S) function to create a function FindBestPlan(S, O),where O is a desired sort order for S, and which considers interesting sortorders. A null order indicates that the order is not relevant. Hints: An algorithmA may give the desired order O; if not a sort operation may need to be added to get the desired order. If A is a merge-join, FindBestPlan must be invoked on the two inputs with the desired orders for the inputs.
Develop an implementation of insertion sort bthat moves larger elements to the right one position with one array access per entry, rather than using exch(). Use SortCompare to evaluate the effectiveness of doing so.
Please offer an illustration of a linear sort method and a short description of linear sort.
Following is the function for interpolation search. This searching algorithm estimates the position (index) of a key in array based on the elements in the first position and last position in the array, and the length of array. The array must be sorted in ascending order. Suppose array A contains the following 15 elements: A = [1, 3, 3, 10, 17, 22, 22, 22, 24, 25, 26, 27, 27, 28, 28] At first iteration, at which position (index) the element of 24 is estimated in array A? In which part of array (starting index and ending index) the searching should continue? How many iterations the searching are performed until the element of 24 is found? int InterpolationSearch(int x[], int key, int n) { int mid, min = 0, max = n-1; while(x[min] < key && x[max] > key) { mid = min + ((key-x[min])*(max-min)) / (x[max]-x[min]); if(x[mid] < key) min = mid + 1; else if(x[mid] > key) max = mid - 1; else return mid; } if…
Please provide an example of a linear sort algorithm and a brief explanation of linear sort.
The element being searched for is not in an array of 100 elements. What is the maximum number of comparisons needed in a sequential search to determine that the element is not there if the elements are completely unsorted?
Please offer an illustration of a linear sort method and a short description of linear sort.
Consider the following list: L = 387, 690, 234, 435, 567, 123, 441. The number of components n = 7, the number of numbers l = 3, and the radix r = 10 are used here. This indicates that radix sort would require 10 bins and would arrange in three passes. demonstrates the radix sort passes over the array. It is believed that each key is tossed face down into the bin. When the keys are gathered in order from each bin at the conclusion of each run, the list of keys in each bin is flipped upside down and added to the output list.
