SICP Exercise 3.24 make-table with same-key?


Exercise 3.24.  In the table implementations above, the keys are tested for equality using equal? (called by assoc). This is not always the appropriate test. For instance, we might have a table with numeric keys in which we don't need an exact match to the number we're looking up, but only a number within some tolerance of it. Design a table constructor make-table that takes as an argument a same-key? procedure that will be used to test ``equality'' of keys. Make-table should return a dispatch procedure that can be used to access appropriate lookup and insert! procedures for a local table.
SOLUTION

The code is here.

Aside from supporting same-key?, I have also implemented a 'print-table' procedure. I expect this to be useful in later exercises too.

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 3.11 make-account internal definitions with local state

Image
Exercise 3.11.    In section  3.2.3  we saw how the environment model described the behavior of procedures with local state. Now we have seen how internal definitions work. A typical message-passing procedure contains both of these aspects. Consider the bank account procedure of section  3.1.1 : (define (make-account balance)   (define (withdraw amount)     (if (>= balance amount)         (begin (set! balance (- balance amount))                balance)         "Insufficient funds"))   (define (deposit amount)     (set! balance (+ balance amount))     balance)   (define (dispatch m)     (cond...

SICP Exercise 3.13 make-cycle

Image
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:
