SICP Exercise 1.41 double

Exercise 1.41.  Define a procedure double that takes a procedure of one argument as argument and returns a procedure that applies the original procedure twice. For example, if inc is a procedure that adds 1 to its argument, then (double inc) should be a procedure that adds 2. What value is returned by



(((double (double double)) inc) 5)

 SOLUTION

SICP Exercise 4.18 a alternative strategy for interpreting internal definitions

Exercise 4.18.   Consider an alternative strategy for scanning out definitions that translates the example in the text to (lambda < vars >   (let ((u '*unassigned*)         (v '*unassigned*))     (let ((a < e1 >)           (b < e2 >))       (set! u a)       (set! v b))     < e3 >)) Here  a  and  b  are meant to represent new variable names, created by the interpreter, that do not appear in the user's program. Consider the  solve  procedure from section  3.5.4 : (define (solve f y0 dt)   (define y (integral (delay dy) y0 dt))   (define dy (stream-map f y))   y) Will this ...

SICP Exercise 3.13 make-cycle

Exercise 3.13.    Consider the following  make-cycle  procedure, which uses the  last-pair  procedure defined in exercise  3.12 : (define (make-cycle x)   (set-cdr! (last-pair x) x)   x) Draw a box-and-pointer diagram that shows the structure  z  created by (define z (make-cycle (list 'a 'b 'c))) What happens if we try to compute  (last-pair z) ? SOLUTION The code is here: Exercise 3.13 make-cycle The box-and-pointer diagrams are here:

SICP Exercise 3.45 deadlock

Exercise 3.45.   Louis Reasoner thinks our bank-account system is unnecessarily complex and error-prone now that deposits and withdrawals aren't automatically serialized. He suggests that  make-account-and-serializer  should have exported the serializer (for use by such procedures as  serialized-exchange ) in addition to (rather than instead of) using it to serialize accounts and deposits as  make-account  did. He proposes to redefine accounts as follows: (define (make-account-and-serializer balance)   (define (withdraw amount)     (if (>= balance amount)         (begin (set! balance (- balance amount))                balance)         "Insufficient funds"))   (define (deposit amoun...
