Use the map and reduce functions defined as (define map (lambda (f 1) (if (null? 1) ' () (cons (f (car 1)) ma f (cdr 1)))))) (define reduce (lambda (op 1 id) (if null? 1) id (op (car 1) (reduce op (cdr 1) id))))) to implement functions minSquareVal and maxSquareVal that determine the minimal square value and maximal square value, respectively, of a list of integer numbers. Example (define minSquareVal (lambda (1) ...)) ... (minSquareVa '(-5 3 -7 10-11 8 7)) rightarrow 9 (define maxSquareVal (lambda (1) ...)) (maxSquareVal ' (-5 3 -7 10-11 8 7)) rightarrow 121 Use the map and reduce functions defined as (define map (lambda (f 1) (if (null? 1) ' () (cons (f (car 1)) ma f (cdr 1)))))) (define reduce (lambda (op 1 id) (if null? 1) id (op (car 1) (reduce op (cdr 1) id))))) to implement functions minSquareVal and maxSquareVal that determine the minimal square value and maximal square value, respectively, of a list of integer numbers.
