Algorithms & Time Complexity 2
{"name":"Algorithms & Time Complexity 2", "url":"https://www.quiz-maker.com/QPREVIEW","txt":"Assume that arr is an array of integers, and #bubble_sort is a standard implementation of the bubble sort method. What is the space complexity of the following function? def best_sort(arr) unsorted = [] arr.each do |el| unsorted << el end all_of_it = [] arr.bubble_sort.each_with_index do |el, idx| all_of_it << [idx, el, unsorted[idx]] end all_of_it end, Assume that arr is an array of integers, and that #merge_sort, #quick_sort, and #bubble_sort are standard implementations of their respective sorts. The methods #merge_sort and #quick_sort do not mutate the original array, but #bubble_sort does. Tail recursion is used in the implementations of #merge_sort and #quick_sort. What is the space complexity of the following function? def all_sorts(arr) one_sort = arr.merge_sort two_sort = arr.quick_sort arr.bubble_sort.each_with_index do |el, idx| return false unless one_sort[idx] == two_sort[idx] && el == one_sort[idx] end true end, You have an app that 100,000 companies use. Users need to be able to see a list of all 100,000 companies, and they need to be able to sort the list by company name and company size. Here's the schema for the company table: id integer ceo_id integer name string num_employees integer industry string job_openings boolean logo_url string","img":"https://www.quiz-maker.com/3012/images/ogquiz.png"}
