IN SCHEME

Write a function subtract which takes a list of numbers as a parameter and returns a list of the differences. So, a list containing the second minus the first, third minus the second, etc.

(subtract '(3 4 10 14 5))

'(1 6 4 -9)

Expert Solution

CODE:

(define (subtract list)
(cond ((null? list) '()) ;;If list is empty returns null list
((null? (cdr list)) '()) ;;If only one element in the list return empty list
(else (cons (- (cadr list) (car list)) (subtract (cdr list)))))) ;;else add (second elelemnt - first element) to list and continue

Write a recursive function, max_in_list(my_list), which takes an non-empty list, my_list, of integers as a parameter. This function calculates and returns the largest value in the list. The base case will probably deal with the scenario where the list has just one value. The recursive case will probably call the function recursively using the original list, but with one item removed. Note: This function has to be recursive; you are not allowed to use loops to solve this problem! Test...

python Write a function pack_to_5(words) that takes a list of string objects as a parameter and returns a new list containing each string in the title-case version. Any strings that have less than 5 characters needs to be expanded with the appropriate number of space characters to make them exactly 5 characters long. For example, consider the following list: words = ['Right', 'SAID', 'jO'] The new list would be: ['Right', 'Said ', 'Jo '] Since the second element only contains...
