Alexander, John -
Nice exchange of ideas here; much obliged to you both.
I've attached timers to each approach, and they're comparable,
at approximately a second each.
Alexander, your non-MACRO: def of `last3` -
: last3 ( seq -- X Y Z )
3 cut* nip first3 ; inline
- is very appealing; I'll make use of this. Hadn't thought of it.
John, as usual, your `solve` word cuts straight to the quick, in
illustrating the use of the `backtrack` vocab.
Factor is my 2nd language, after Forth (via Neon, circa 1984!),
& a really great system to explore modern programming.
Onward,
~cw
