Write a Scheme function that takes two integers and returns the list of all integer numbers between these two integers (inclusively) in increasing order. (numbers 10 20) (10 11 12 13 14 15 16 17 18 19 20)

Please explain every step.

Expert Solution

(define (numbers x y)
   ; if both equals then return list of y
   (cond ((equal? x y) (list y))
       ; if x > y then return a list from y to x
       ((> x y) (cons y (numbers (+ y 1) x)))
       ; else return a list from x to y
       (else (cons x (numbers (+ x 1) y)))
   )
)

; (numbers 10 20)

1.Write a function div7(lst) which takes in a list of integers, and returns a list of booleans of the same length, such that for each integer in the original list, the boolean in the output list is True if that integer was divisible by 7, or False if not. Use list comprehensions in python, the function only could be at most two lines long. Here is some examples: >>> div7([14, 5, 7, 3, 29, 28, 10]) [True, False, True, False,...

Design a function called middle_value, that takes 3 integers, and returns the integer with the middle value. If there is a tie, any of the possible middle values can be returned. Example: middle_value(1, 2, 8) -> 2 middle_value(9, 7, 7) -> 7 middle_value(3, 3, 3) -> 3 Design a function called combine_strings that takes two phrases and appends the longer string onto the back of the shorter one with no space between the two phrases joined. Example: If the phrases...
