6-Fully explain each predict in the following scheme function. Then manually trace the function with the given input. (define (max num1 num2) (if (> num1 num2) num1 num2)) (define (Q6Func a_list) (cond ((null? a_list) 1) ((list? (car a_list)) (max (+ 1 (Q6Func (car a_list)) ) (Q6Func (cdr a_list)))) (else (Q6Func (cdr a_list)) ) )) (Q6Func((A (((B C) ((D)) ) ) E) F) )
