Develop an implementation of insertion sort that eliminates the j>0 test in the inner loop by first putting the smallest item into position. Use SortCompare to evaluate the effectiveness of doing so. Note : It is often possible to avoid an index-out-of-bounds test in this way—the element that enables the test to be eliminated is known as a sentinel.
The median value of a set of n numbers is the value that separates the half of higher values from the half of lower values in the set. The median can be found by arranging the values in the set in order and choosing the “middle” value. See the lecture slides for some sorting functions we will talk about tomorrow that will get any list in order. If there are an even number of values in the set, the median is described as the mean of the two middle values. (b) Write a SCHEME function, named list-median, that takes a list of numbers as a parameter and returns the median value in the list.
AssuAssume we want to analyze empirically 4 variants of the Quicksort algorithm by varying the selection of the pivot and the recursive call as follows: ● Try the following values when selecting a pivot: - Pick the last element as pivot - Pick a random element as pivot ● Do not make a recursive call to QuickSort when the list size falls below a given threshold, and use Insertion Sort to complete the sorting process instead. Try the following values for the threshold size: - Log2(N) - Sqrt(N) Therefore, you are asked: a. (12 points) Write the java code for the 4 Quicksort implementations. b. (5 points) Write a driver program that allows you to measure the running time in milliseconds of the 4 implementations for N = 10000, 20000, 40000, 80000 and 160000. For each data size N, generate a random list of N random integers ranging from 1 to 107 and use the same list to measure the running time of the 4 implementations. Present the results in the following table:me we want to analyze…
Q: Suppose you are given an array A of n elements. Your task is to sort n numbers stored in array A by reading the first element of A and placing it on its original position (position after sorting). Then read the second element of A, and place it on its original position. Continue in this manner for the first n-1 elements of A. What type of sorting is this? Write the algorithm and also mention the name of this sorting algorithm. What loop invariant does this algorithm maintain? Give the best-case and worst-case running times of this sorting algorithm.
this is a data structure algorithm question so read it properly and right correct answer please

Plese Explain Q 5. Thank you.
01... ""Implementation of the Misra-Gries algorithm.Given a list of items and a value k, it returns the every item in the listthat appears at least n/k times, where n is the length of the array By default, k is set to 2, solving the majority problem. For the majority problem, this algorithm only guarantees that if there isan element that appears more than n/2 times, it will be outputed. If thereis no such element, any arbitrary element is returned by the algorithm.Therefore, we need to iterate through again at the end. But since we have filtredout the suspects, the memory complexity is significantly lower thanit would be to create counter for every element in the list. For example:Input misras_gries([1,4,4,4,5,4,4])Output {'4':5}Input misras_gries([0,0,0,1,1,1,1])Output {'1':4}Input misras_gries([0,0,0,0,1,1,1,2,2],3)Output {'0':4,'1':3}Input misras_gries([0,0,0,1,1,1]Output None"""..
Alter insertion sort below to sort a list of strings instead of numbers. It shouldn't return anything - it should sort the list "in place". The sorting should ignore case. For example "Zebra" should come after "apple", "maRker" should come after "marble", etc. Name this function string_sort. After calling this function, the list that was passed in should now contain the exact same strings it did before, but in sorted order. def insertion_sort(a_list): """ Sorts a_list in ascending order """ for index in range(1, len(a_list)): value = a_list[index] pos = index - 1 while pos >= 0 and a_list[pos] > value: a_list[pos + 1] = a_list[pos] pos -= 1 a_list[pos + 1] = value
