Make a function called choose with two parameters n and k, that implements the above formula.
In Kotlin, write a higher-order function with an expression body that takes an int n and a function f from int to int and returns the result of calling f(f(n)). For example if you call the function with n = -5 anda function that calculates absolute value, your function will return 5, and if you send the value 2 and a function that calculates the sqaure of an int, the function will return 16. in addition to the function, write the syntax to call it with:a. a function name as the function arguementb. some lambda expression as the function argument

In python, The function slice_end takes a string parameter, word, and a positive integer n; the function returns a slice of length n from the end of word. However, if word has length less than n, then the None object is returned instead. Hint: Notice that returning the empty string when n is zero might be a special case. You can use an if-elif-else decision structure and the slicing operator [ : ] to solve this problem. For example: Test Result word = "pineapple" n = 5 print(slice_end(word, n)) apple word = "too short" n = 20 print(slice_end(word, n)) None word = "llama" n = 0 print(slice_end(word, n)) word = "Saturn" n = 6 print(slice_end(word, n)) Saturn
A sequence (bn)neN is called strictly increasing if b, M. We can represent a sequence (bn) by a Python function that takes n as its argument (of type int) and returns bn (of type float). Write a function threshold_index that takes two arguments: The first one is a Python function representing a strictly increasing, divergent sequence. The second one is a threshold value M. The function threshold_index should return the smallest index n for which the sequence passes the threshold (i.e., bn ≥ M).

-Python- Write a function get_letter_grade, such that when given * a lab grade score and * a list of the grade cutoffsreturns the letter grade of that score.Note: Your function automatically returns A for the values that are >= to the first cutoff-value in the list, then A- for the second cutoff-value, B+ for the third and so on. The function returns None for anything that's below the score for B-. You test that get_letter_grade(97, [93, 90, 87, 83, 80]) correctly returns an A, and get_letter_grade(93, [97, 90, 87, 83, 80]) returns A-. DO NOT hard-code the cutoffs, since they can change! You can copy/paste the following template: def get_letter_grade(score, cutoffs): if score ... : return 'A' ...: return 'A-' ...: return 'B+' ...: return 'B' ...: return 'B-'
Write a recursive Racket function "update-if" that takes two functions, f and g, and a list xs as parameters and evaluates to a list. f will be a function that takes one parameter and evaluates true or false. g will be a function that takes one parameter and evaluates to some output. The result of update-if should be a list of items such that if x is in xs and (f x) is true, then (g x) is in the list. The output list's elements should keep the input list's items in the same relative order. For example (update-if even? add1 '(1 2 3 4)) should evaluate to '(3 5) because 2 and 4 make even? true and add1 turns 2 and 4 into 3 and 5.
