RE: [racket-users] numerical partitions

2017-11-09 Thread Jos Koot 
How did you implement procedure part many years ago?
Things may depend on what you want to do with the partitions.
Do you want the whole list at once,
or would a stream or generator be more appropriate?
If you want I can send you a stream-version,
but it is in a bad style.
It has docs made with scribble.

Many years ago (r5rs days) I asked for help in partitioning numbers i.e.

(part 4) returns ((4) (3 1)  (2 2) (2 1 1) (1 1 1 1))

where the order of solutions is not important. Is it more efficient to 
implement using Racket's iteration macros? Any help would be
appreciated.
