Write a Scheme function that takes a positive integer n and returns the list of all...

Write a Scheme function that takes a positive integer n and returns the list of all first n positive integers in decreasing order:

(decreasing-numbers 10) (10 9 8 7 6 5 4 3 2 1)

Please explain every step

Expert Solution

Code:

(define (decreasing-numbers n)
(cond (( = n 0) '()) ;;if n = 0 returns empty list
((= n 1) (list 1)) ;;if n = 1 returns list which contains 1 i.e, '(1)
(else (cons n (decreasing-numbers (- n 1)))))) ;;else cons the element and recursively call with n-1

PYTHON 3: Write a recursive function that takes a non-negative integer n as input and returns the number of 1's in the binary representation of n. Use the fact that this is equal to the number of 1's in the representation of n//2 (integer division) plus 1 if n is odd. >>>numOnes(0) 0 >>>numOnes(1) 1 >>>numOnes(14) 3

Write a function convert_date that takes an integer as a parameter and returns three integer values representing the input converted into days, month and year (see the function docstring). Write a program named t03.py that tests the function by asking the user to enter a number and displaying the output day, month and year. Save the function in a PyDev library module named functions.py A sample run for t03.py: Enter a date in the format MMDDYYYY: 05272017 The output will...

Write a function that will accept a list of numbers and an integer (n). The function should return a list containing every nth item from the input list, always starting with the first item in the list. The original list should not be modified. For example, if the function is passed the list [8, 3, 19, 26, 32, 12, 3, 7, 21, 16] and the integer 3, it will return the list [8, 26, 3, 16] If the function is...
