There is a recursive function called `longestToShortest` which takes an array of lowercase ot strings and returns them sorted from longest to shortest. Strings of equal length should be sorted alphabetically. Your function should accept a default argument called `sorted` which holds the currently sorted elements. Each recursive step should add the shortest string in the `strings` array to the end of `sorted`. // Examples: // Sorts strings from shortest to longest let strings1 = ["abc", "de", "", "f", "ghijk", "lmno"] shortestToLongest(strings1); // ['', 'f', 'de', 'abc', 'lmno', 'ghijk'] function longestToShortest(strings, sorted = []) { } Please explain all steps Line by line, Show all work inside the function to pass the example console.log test cases. Please do it in the recursive function only. Thank you!
Assume you have a sorted list of 100 pre-sorted elements and a recursive implementation of Quicksort. How many calls to Quicksort are made in order to fully sort it. Assume that the algorithm makes the recursive Quicksort calls before checking if it has an array of size 1 (see https://www.geeksforgeeks.org/quick-sort/ for specific pseudo code or the textbook Introduction to Algorithms 3rd Edition page 171). 85 101 50 103 199 Assume you have the following array: 40, 20, 15, 40, 90, 60, 50, 70.

Please answer it in Python Sorting a list is to take the minimum and put it at the beginning, then start again with the second smallest, etc. min in final order remaining entries Write a function sort card that sorts an integer list by successive selections of the smallest element of the unsorted part of the list. For example: [1,-12, 19, 0] #return [-12, 0, 1, 19] [5, 4, 3, 2, 1] # return [1, 2, 3, 4, 5]
Write a sort function that uses the bubble-sort algorithm. The bubble-sort algorithm makes several passes through the list. On each pass, successive neighboring pairs are compared. If a pair is in decreasing order, its values are swapped; otherwise, the values remain unchanged. The technique is called a bubble sort or sinking sort because the smaller values gradually “bubble” their way to the top and the larger values “sink” to the bottom. Write a test program that reads in ten numbers, invokes the function, and displays the sorted numbers.
Answer please.
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…
compare and contrast static array-based unsorted list and static array-based sorted list, There is a function binary search in the sorted list one. Which two public functions are using the binary search function so that it can be faster than utilizing a linear search?
1. Write a program that compares all four advanced sorting algorithms discussed in this chapter. To perform the tests, create a randomly generatedarray of 1,000 elements. What is the ranking of the algorithms? What happens when you increase the array size to 10,000 elements and then 100,000elements?
12 - Consider the example of sorting, we implemented Bubble sort but the data started to grow and Bubble sort started getting very slow. In order to tackle this we implemented Quick sort. But now although the Quick sort algorithm was doing better for large datasets, it was very slow for smaller datasets. In order to handle this situation, implement a --------- small datasets, bubble sort will be used and for larger, quick sort will be used. design pattern where for According to the system definition given above, which design pattern did designers use when implementing the system.

Select all the statements that are false, bubble sort is defined below:* Quicksort is the fastest sorting algorithm If you are lucky, you can get O(n) time complexity in Mergesort On the worst case, Bubble sort will give you O(n logn) time complexity Average time complexity of insertion sort is much better than bubble sort Selection sort has the worst space complexity among all the sorting algorithm
