Define a recursive function reverse in Scheme which accepts only an S-list s as an argument and reverses the elements of s in linear time (i.e., time directly proportional to the size of s), O(n). You may use only define, lambda, let, cond, null?, cons, car, and cdr in reverse. You may not use append or letrec in your solution. 1 > (reverse' 1 2 3 4 5)) 2 (5 4 3 2 1) 3 > reverse' (1)) 4 (1) 5 > (reverse' (21)) 6 (12) 7 > (reverse' (night and day)) 8 (day and night) 9 > reverse' (1 (2 (3))(4 5))) 10 ((45)(2 (3)) 1)
