GIVENTHAT :

To write a Scheme function that takes a simple list of numbers as a parameter and returns a list with the largest and smallest numbers in the input list.

code:

(define (max list)(cond((null? list) '())((null? (cdr list)) (car list))((> (car list) (max (cdr list))) (car list))(else (max (cdr list)))))

(define (min list)(cond((null? list) '())((null? (cdr list)) (car list))((< (car list) (min (cdr list))) (car list))(else (min (cdr list)))))

(define (minmax list) (cons (min list) (cons (max list) '())))

(display (minmax '(6 1 9 3 10 -6 2)))

Output :

(-6 10)

Define a function in Scheme which takes a list of numbers and a scalar and returns the rest of the list after the first occurrence of the scalar that was passed. An empty list should be returned if the value doesn't exist. For example, (list-past-scalar '(5 2 8 3 1 9 2 3) 3) #returns (1 9 2 3) (list-past-scalar '(37 18 38 65 90) 100) #returns ()

1) Write a function in C that takes in a single integer parameter and returns an array of factors. The function signature should be : int* get_factors(int number) To make things a little easier, assume that the input (number) will never have more than 100 factors. The returned array should be null-terminated. 2) Write a main() function that asks a user for a number, calls the function above, then prints the results.

Write a largestBelowValue(numbers, value) function that returns the largest number in the list numbers that is smaller than value. Assume the numbers are always positive integers. Some example test cases (include these test cases in your program): >>>print(largestBelowValue([31, 5, 71, 53, 40, 17], 40)) 31 >>>print(largestBelowValue([31, 5, 71, 53, 40, 17], 41)) 40 returns None since no value is smaller than 2 in the list >>>print(largestBelowValue([31, 5, 71, 53, 40, 17], 2)) None
