Write a Python function that generates all possible combinations of a given list of integers, without using any built-in libraries (e.g., itertools). The function should take two parameters: the list of integers and the length of the combinations. Ensure that the function handles duplicate elements in the input list and avoids generating duplicate combinations.

The function should be written in python language. Write a function called "stats" to return the mean, median, and standard deviation (in that order) of a list of integers, where the list of integers is given as a parameter. The stats must be returned in a list. Example: [In]: stats([15, 4, 10, 2]) [Out]: [7.75, 7.0, 5.909032633745278]
Write a python function MedianWithoutHL(ScoreList) that takes an unsorted list of n numbers as a parameter, discards the highest and the lowest numbers and return the median. You can assume the number of items in the list is between 0.0 and 9.9. To find the median from a list of items, you have to sort the list and find out the value of the item in the middle.Note: If the list has an odd number of items, the median is the value of the middle item. If the list has an even number of items, the median is the average of the two middle items.Sample Run #1:scoreList1 = [9.0, 9.0, 7.5, 8.0, 9.5, 6.5, 5.0, 7.0, 7.5, 8.5]print("The Original ScoreList: ", scoreList1)print(MedianWithoutHL(scoreList1))Output of Sample Run #1:The Original ScoreList: [9.0, 9.0, 7.5, 8.0, 9.5, 6.5, 5.0, 7.0, 7.5, 8.5]The List after sorting: [5.0, 6.5, 7.0, 7.5, 7.5, 8.0, 8.5, 9.0, 9.0, 9.5]Without the High & Low: [6.5, 7.0, 7.5, 7.5, 8.0, 8.5, 9.0, 9.0]7.75
Assume that L is a list of Boolean values, True and False. Write a program in python with a function longestFalse(L) which returns a tuple (start, end) representing the start and end indices of the longest run of False values in L. If there is a tie, then return the first such run. For example, if L is False False True False False False False True True False False 0 1 2 3 4 5 6 7 8 9 10 then the function would return (3, 6), since the longest run of False is from 3 to 6.

Write a function randomList() that gets three integers as parameters, start, bound and k. This function will create a list of k randomly generated integer numbers between start and bound values (both inclusive), and return the created list.Write a function sqrtList() that gets a list as parameter, print the numbers in the list and their square root. The square roots will be printed with 3 decimal digits. Write Python statements that ask the user to input start, bound and k values, then call the method to perform the calculations and produce the output.At the end print average of numbers by calling the function calculateAverage(). Part-2:Enter start: 10Enter end: 30Enter k: 41. number: 28 Square root = 5.2922. number: 22 Square root = 4.6903. number: 10 Square root = 3.1624. number: 16 Square root = 4.000Average of numbers is = 19.0
in python. Please include docstring. Write a recursive function named list_max that takes as its parameter a list of numbers and returns the maximum value in the list. You can assume the list contains at least one element. If multiple elements of the list are tied for the maximum, you would still return that value. You cannot call the built-in max() function. You may use default arguments and/or helper functions. Your recursive function must not: use any loops use any variables declared outside of the function use any mutable default arguments (see the Code Style Requirements)

Ask the user to enter a series of integers, and store these numbers into a linked list. The user can enter as many numbers as she like, so your program must keep asking for more until she enters -100 to signify she wants to stop. Please note that your program must store the number into a *linked list*, and not an array, because in theory, the user can enter unlimited number of integers, and all array has a fixed size. * Implement a C function to perform merge sort. This function takes the linked list above as the input, and sort it using the Merge Sort algorithm. You do have a choice here: You can either perform the merge sort directly on the linked list (more fun), or copy the numbers from the linked lists into an array first, and then sort the array (more familiar).
Implement a list of employees using a dynamic array of strings.Your solution should include functions for printing list, inserting and removingemployees, and sorting lists (use Bubble sort in C++ language).Keep list of employees sorted within the list after insertion.See the following example:How many employees do you expect to have?5 (Carriage Return)Menu :1 . Print full list of employees2 . Insert new employee3 . Remove employee from list0 . Exit2 (Carriage Return)Input name of new employee : MikeMenu :1 . Print full list of employees2 . Insert new employee3 . Remove employee from list0 . Exit1(Carriage Return)1 . MaryMenu :1 . Print full list of employees2 . Insert new employee3 . Remove employee from list0 . Exit
Write a function find_max_tuple() that gets a list of tuples as parameter, finds and returns the tuple with maximum sum inside the list. Write Python statements that create a sample list that has tuples inside (you can use the list of tuples in the sample run below), then use find_max_tuple() function to get the tuple with maximum sum and print it. Sample tuples=[(3,4,360,6),(1,2),(12,),(132,244,64),(72,71,70)] The maximum tuple is (132,244,64)

Write a recursive function that finds the minimum value in an ArrayList. Your function signature should be public static int findMinimum(ArrayList<Integer>) One way to think of finding a minimum recursively is to think “the minimum number is either the last element in the ArrayList, or the minimum value in the rest of the ArrayList”. For example, if you have the ArrayList [1, 3, 2, 567, 23, 45, 9], the minimum value in this ArrayList is either 9 or the minimum value in [1, 3, 2, 567, 23, 45] Hint:The trick is to remove the last element each time to make the ArrayList a little shorter. import java.util.*; public class RecursiveMin{public static void main(String[] args){Scanner input = new Scanner(System.in);ArrayList<Integer> numbers = new ArrayList<Integer>();while (true){System.out.println("Please enter numbers. Enter -1 to quit: ");int number = input.nextInt();if (number == -1){break;}else {numbers.add(number);}} int minimum =…
