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 ()

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

Your function should return a list of two floating-point numbers; the first will be the sum of the deposits, and the second (a negative number) will be the sum of the withdrawals. >>> statement([30.95, -15.67, 45.56, -55.00, 43.78]) [120.29, -70.67]

Write a Python function first_chars that takes one parameter, which is a nested list of strings. It returns a string containing the first character of all of the non-empty strings (at whatever depth they occur in the nested list) concatenated together. Here are a couple of examples of how the function should behave when you're done: >>> first_chars(['Boo', 'is', 'happy', 'today']) 'Biht' >>>first_chars(['boo', 'was', ['sleeping', 'deeply'], 'that', 'night', ['as', ['usual']]]) 'bwsdtnau'
