Output the execution time for the quick sort, selection sort, insertion sort, bubblesort, and merge sort algorithms as they attempt to sort an array of 1000 randomnumbers, 1000 sorted number, and 1000 numbers in reversed order.For this use the the high_resolution_clock::now() function that will return the currenttime. To use this you will also need to include the header file as well asusing namespace std::chrono.Quick sort187 ms for random numbers176 ms for sorted numbers173 ms for reversed numbersSelection sort1300 ms for random numbers1424 ms for sorted numbers2578 ms for reversed numbersInsertion sort401 ms for random numbers1 ms for sorted numbers1 ms for reversed numbersBubble sort1366 ms for random numbers669 ms for sorted numbers667 ms for reversed numbersMerge sort1297 ms for random numbers1049 ms for sorted numbers1010 ms for reversed numbers

Exercise - Collection Functions Using the code below, use the map function to create an array of Int values, whose values are equal to the original integer value, plus 1. Use $0 as you iterate through the values of the array. Print the resulting collection. 5 let testScores = [65, 80, 88, 90, 47] Using the code below, use the filter function to create a new array of String values. The new array should only include Strings longer than four characters. Use $0 as you iterate through the values of the array. Print the resulting collection. Olet schoolSubjects = ["Math" , "Computer Science", "Gym", "English", "Biology"] Using the code below, use the reduce function to subtract all of the values within the array from the starting value 100. Print the resulting value. let damageTaken = [25, 10, 15, 30, 20]
Need some help on this Python Quesion
13. While dictionaries are designed so that we can find a value based on a key, every so often we need to perform a reverse lookup. For example, imagine a dictionary where the keys are names and the values are phone numbers. Usually we want to find the phone number based on the name, but occasionally you might need to find a name based on the phone number. Write a function called reverse_lookup(dictionary, value) that returns all the keys in the dictionary associated with the specified value. Note: In dictionaries, the keys are guaranteed to be unique, but the values are not. So your function should return a list containing all of the matching keys (if any) Example: Given this dictionary, groups = {'Apple': 'Fruit', 'Spinach': 'Vegetable', 'Banana': 'Fruit'} reverse_lookup (groups. Vegetable') ["Spinach'] reverse_lookup (groups, Fruit') ['Apple'. 'Banana'] reverse_lookup (groups. 'Meat') []

PYTHON QUESTION This assignment requires you to create a dictionary by reading the text file created for the Chapter 6 assignment. The dictionary should have player names for the keys. The value for each key must be a two-element list holding the player's goals and assists, respectively. See page 472! Start with an empty dictionary. Then, use a loop to cycle through the text file and add key-value pairs to the dictionary. Close the text file and process the dictionary to print the stats and determine the top scorer as before. In fact, much of the code used in program6_2.py can be copied and used for this program. Printing the stats for each player is the most challenging part of this program. To master this, refer to the examples in the zip file that can be downloaded from the "Dictionary values can be lists" link in the "Learn Here" part of this module. NOTE: you do not need to submit the text file. Submit just this program. The required output should be the same well-formatted table…
