Exercise 4.36: Exercise 3.69 discussed how
|
||
|
|
to generate the stream of all Pythagorean triples, with no upper bound
|
||
|
|
on the size of the integers to be searched. Explain why simply replacing
|
||
|
|
an-integer-between by an-integer-starting-from in the procedure
|
||
|
|
in Exercise 4.35 is not an adequate way to generate arbitrary Pythagorean
|
||
|
|
triples. Write a procedure that actually will accomplish this. (That is,
|
||
|
|
write a procedure for which repeatedly typing try-again would in
|
||
|
|
principle eventually generate all Pythagorean triples.)
